Information gathering. Unlock Secrets of the Cosmos

AMS-02 is a multipurpose magnetic spectrometer designed to measure elementary particles and nuclei to the TeV region. In the five years since its installation on the International Space Station, it has collected more than 90 billion cosmic rays. Some of the unexpected results and their possible interpretations will be presented.

The Commissioning of the ATLAS

Atlas Experiment :Tile Calorimeter Barrel

The commissioning of the ATLAS detector with physics data started more than three years ago with cosmic rays. This has enabled us to put in place the full operation chain, from the trigger and data acquisition up to the analysis all over the world. Thanks to this intense commissioning campaign, ATLAS was ready to collect data already during the first day of LHC single beam operations on the 10th of September in 2008.

 There is no doubt that I would move fast forward to the culmination of everything that is a part of the atlas experiment to have said the final result is what is to be gained by measure. The Calorimeter view just seemed natural as the going on of Glast,  now called Fermi would have shown it's own construction as a necessary element of that measure in calorimeter design. So of course jumping ahead one needed to carry certain assumptions, and for me this was about the cosmic particle events that lay at the foundation of the universe in it's informative style as reductionist in nature.

There is a little confusion on my part here about the simultaneous view that what is in the pipeline has a strong correlation to what we seek of,  in cosmic particle collisions. The energies involved,  as decay products. So as I looked at this article and the phenomenological correspondence necessary I needed to understand that effects of such operations,  current in the cosmos could have somehow contaminated the results they were seeking through controlled processes. So how was this done is the issue here and how such data cannot be influenced by what is currently happening in the cosmos.

As a layman it was of interest that my developing perspective about the cosmos at this scale sought some kind of revelation in the way research would have been done experimentally. So this was a challenge to me that I could see the scale at which the cosmos picture was developing microscopically on a large scale could have been part and parcel exemplified in this research as the cosmological view. It just seemed natural to me the effect of what was happening on earth was somehow translated in how the earth itself sat in the cosmos as a participant bathed in the cosmos glory.

In a sense I have felt belittled by the idea that my seeking of the workings of the cosmos would have fell to such materialistic views. Of course I want to know how it all works.  But truly this is the way I am sure that would lead to the understanding of something very important about the way in which we can view the universe. At some point,  there is an exchange taking pace about how such matters form, and there is no other way in which to derive this but to further dissect the nature of particulate expression but by energy disposition?

COSMOS:AIRES Cosmic Ray Showers

Throughout the course of my research there has been a connecting thread that has brought me to certain conclusions about matter states as they exist in the cosmos, but by identifying the particulates of the realty in which we live. So in a way it is necessary to observe that nature we are seeing as so obvious in our observation on a fundamental level, can go much deeper as we implored the the use and need of the spectrum in this wider view of the cosmos. The backdrops necessary in determining what the energy is saying as we record the events in the calorimetry design,  how ever this is constructed.

In this same way as cosmic particle collisions are derivative of the events in the cosmos, for Atlas research,  CMS serves to support Atlas, and vice versa?? :)

See 21-23 January 2013 CERN

The primary goal of this 3‐day workshop is to educate the LHC community about the scientific utility of likelihoods. We shall do so by describing and discussing several real‐world examples of the use of likelihoods, including a one‐day in‐depth examination of likelihoods in the Higgs boson studies by ATLAS and CMS.
The workshop will start with two pedagogical lectures that introduce likelihood concepts and terminology. These lectures are followed, in the afternoon of Day 1, by a moderated discussion that focuses on the concepts and issues raised in the lectures. Day 1 ends with several presentations that illustrate the use of likelihoods in Higgs and Beyond the Standard Model (BSM) research. The goal here is to get feedback from researchers who have used Higgs and BSM results in their work.See: Likelihood for the LHC Searches

You know analogies are important in that they can bring a lay person some clarity in helping to understand what s going on in the world of science. As a blogger I have attach myself to some scientists who have been more then willing to share this aspect of them-self with the world. I do not know of a more honorable thing a scientist can do but by taking this time to help the public.

    XKCD Significant-Speed of Light Issue?

    You got to love it when correlations can be made, and a thank you to the ICECUBE Blog
    If the histograms and data are exactly right, the paper quotes a one-in-ten-thousand (0.0001) chance that this bump is a fluke. That's pretty small; although bear in mind that lots of distributions like this get plotted. If you plot 100 different distributions, the chances become about one in a hundred (0.01) that you'll see something odd in one of them. The Tevatron goes bump

    So what about the Missing Energy?

    "Death, so called, is but older matter dressed
    In some new form. And in a varied vest,
    From tenement to tenement though tossed,
    The soul is still the same, the figure only lost." Poem on Pythagoras, Dryden's Ovid.

    It is unfortunate to have endured the constant flutter of disbelief(cry of pseudoscience) as to what is possible in a given space, that we can say that we do not really have all the facts to it's understanding, yet, to know that in this region, new physics will be produced.

    It is also unfortunate to have observed a whole generation of string theorists who have undergone this constant rebuttal and berating over and over again while standing strong to the "educative values" undermined by those who saw no benefit too. You maintained the perseverance of a "thought domain that cover regions within the valleys" to be speaking about a time just after the big bang. How would the normal population of scientists know this?

    Thanks to the high collision energy and luminosity of the LHC, the ATLAS detector will be capable of revealing the existence of extra spatial dimensions in some substantial region of parameter space. The talk will summarize recent studies from the collaboration on different possible signals predicted by models where the dimensions are "large", where they are of size ~TeV^-1 or where they are "warped". These signals include direct emission of Kaluza-Klein states of gravitons, virtual effects of graviton exchange and gauge boson excitations. We shall also discuss the possibilities of observing black holes. mini review for search of eXTRA Dimentions

    Now this question is an important one to me, because it is based on the amount of energy used in the collision process, and what is to come out of that collision process as tracks, adds up to so much energy. If these two numbers do not equal in parity then where has that extra energy gone?

    This has always been a fundamental question to me of where I thought "new physics was to be found" and to have Tammaso Dorigo confirm this is quite a statement indeed of what is leading perspective in terms of what is to be measured and what is going to be measured in the proposed LHC experiments.

    Missing Energy Kicks New Physics Models Off The Board

    The signature of large missing energy and jets is arguably one of the most important avenues for the study of potential new physics signatures at today's hadron colliders.

    The above concept marks an interesting turn of events: the years of the glorification of charged leptons as the single most important tools for the discovery of rare production processes appears behind us. The W and Z discovery in 1983 by UA1 at CERN, or the top quark discovery by CDF and DZERO in 1995 at Fermilab, would have been impossible without the precise and clean detection of electrons and muons. However, with time we have understood that missing energy may be a more powerful tool for new discoveries.

    Missing energy arises when a violent collision between the projectiles -protons against antiprotons at the Tevatron collider, or protons against protons at the world's most powerful accelerator, the LHC- produces an asymmetric flow of energetic bodies out of the collision point in the plane orthogonal to the beams: a transverse imbalance. This is a clear signal that something is leaving the detector unseen. And it turns out that there is a host of new physics signals which can do precisely that.

    A large amount of missing transverse energy may be the result of the decay of a leptoquarks into jets and neutrinos, when the latter leave undetected; or from the silent escape of a supersymmetric neutral particle -the neutralino- produced in the chain of decays following the production of squarks and gluinos; or it may even be due to the escape of particles in a fourth dimension of space -an alternative dubbed "large extra dimensions".
    see more in linked title above)

    Now this is the thing that has troubled me most about scientists who are working and in the know, had not realized the necessity of pushing perspective back to a time to the first moments of the big bang(not just Steven Weinberg's first three minutes but of the microseconds just after the big bang) in order to understand what we are working on in terms of unification, and of where the products of this missing energy will spring forth from, as we move forward in the experiments to come.

    The understanding then has always been in what is in that missing energy, to determine what new physics shall be, that such understanding was already there for the string theorist in their considerations. The contact point has already been defined for them, and reached two extremes. There is a reason why the missing energy escapes.

    You had to know already where and what this "contact point meant" and what was to come out of it to know that dynamical qualities could exist in the big bang and where this big bang resides in the cosmos. That such energies can be reached there now. This required us to know that local events in the cosmos could contribute to the very nature of the cosmos and the state of the cosmos in the now. Like some cosmological constant "hidden and growing" in Omega.

    To know that the dissipative results from micro collisions decaying fast too, did not mean we would be running short of the elements of this new physics either. It left it's remnants all around us to know that what can come out of such a collision point is not the story of the FLashForward scenario, but of things that travel through the earth to meet Gran Sasso and the likes. It was a whole plethora of particle disseminations that left missing energy around for us to explore in potential as some fictional substrate of the reality of nature that had not been seen before.

    Cascading Showers from the Cosmos

    3) It is claimed that cosmic rays can energy exceeding that of colliders, and they have not caused trouble, suggesting that colliders will not cause trouble either. However, the analogy is not precise. It assumes two things that may not be true. First, cosmic ray center of mass energy exceeding that of colliders has never been measured directly. Measurements that seem to show this are based on showers of secondary particles. Second, the product of a collision between a cosmic ray and an earth particle will always be moving at an appreciable fraction of the speed of light. If it has a small capture radius, it will always pass right through earth like a neutrino. The product of a collider collision can (sometimes) be moving at less than escape velocity from earth. If so, it will fall into earth where it will have forever to accrete other matter. Some calculations show rapid accretion.
    See: Risk Evaluation Forum

    Using this above as one basis of the argument, it was by these assumptions that I too was convinced things would be okay. There are a lot of things that go with this statement that currently is not expressed given current information in regards to Pierre Auger experiments. That when clearly seen in the light of current research into LHC, does not allow one to take in all that they should be.


    Go back to John Ellis and current research if you must, and thinking in terms of the cosmos. It's infancy, and one does not disregard the "origins and beginnings" of this universe. Are there reasons that are less then desired that would govern any legal defence team based on some "religious affiliation" and driven from this religious context? I hope not.

    We would not want some Woitian backlash, as done with string theory, from a intelligent design standpoint, as a recognized motived factor in that legal defense. It is far beyond me that I ask these associative questions, yet, these images come to mind when ever the establishment hosting the world's collective scientists, is confronted by the very issues that seem evasive in regards to safety?

    Energies Used in Particle Creation

    It would behove any person to take the time to travel to the links I am supplying, to help you absorb as much information as possible.With the full intention that what I am describing does have a distillation process that will become very simple in qualitative design.

    Finding the energy range with which we are dealing within our colliders, has awakened the realization of the complexity dimensional attributes would have considering E8.

    "I’m a Platonist — a follower of Plato — who believes that one didn’t invent these sorts of things, that one discovers them. In a sense, all these mathematical facts are right there waiting to be discovered."Donald (H. S. M.) Coxeter

    The complexity of the blackhole would have allowed the possibilities of describing the source of "all dimensional attributes" knowing that the collapse of the blackhole would bring temperatures to the point of the quark Gluon plasma. What would be happening to allow such complexity?

    This basis of thought on my part is, "the equivalence determined" and thought about in terms of Lagrangian considerations. This another topic. But does deal with the understanding of the potential microscopic blackholes that could be produced, determined by the energy levels

    Thus RHIC is in a certain sense a string theory testing machine, analyzing the formation and decay of dual black holes, and giving information about the black hole interior.

    See:Are Strangelets Natural?

    LHC Safety?

    I am writing this blog entry because of Walter's comments on the side.

    It is very hard for me knowing that there is a train of thought developed through my research. This question of cascading showers, were with the understanding of "energy events" that allowed us to see a "greater plethora of mapping" that would direct us to the very essence of symmetry breaking, based on experimental processes herein this blog described.

    "String theory and other possibilities can distort the relative numbers of 'down' and 'up' neutrinos," said Jonathan Feng, associate professor in the Department of Physics and Astronomy at UC Irvine. "For example, extra dimensions may cause neutrinos to create microscopic black holes, which instantly evaporate and create spectacular showers of particles in the Earth's atmosphere and in the Antarctic ice cap. This increases the number of 'down' neutrinos detected. At the same time, the creation of black holes causes 'up' neutrinos to be caught in the Earth's crust, reducing the number of 'up' neutrinos. The relative 'up' and 'down' rates provide evidence for distortions in neutrino properties that are predicted by new theories."

    See: How Particles Came to Be

    In doing my own research, I tried to follow the thinking of the literature presented on the topic of microscopic blackholes. Now there was to my understanding a theoretical position assumed, from what we understood when dealing with the topic, and the understanding of what Cern was to produce.

    Fig. 2. Image showing how an 8 TeV black hole might look in the ATLAS detector (with the caveat that there are still uncertainties in the theoretical calculations).

    Now to me the basis of settling the questions of safety, were answered by association of "what was natural" within the domains of these cascading particle showers in terms of these cosmic rays.

    If we were after the origins and beginnings to our universe, we were in essence, describing and mapping the beginning times of these particle showers. Also, the dimensional attributes of the interior of the blackhole.
