The Developmental Jet Process

As a layman I have been going through the research of those better educated then I in order to construct a accurate syntactically written developed scientific process as I have become aware of it. This is what I have been doing for the last number of years so as to get some idea of the scientific process experimentally driven to this point.

Theoretical development is important to myself,  as well as,   the underlying quest for a foundational perspective of how we can push back perspective with regard to the timeline of the universe in expression.

This has to be experimentally written in the processes we now use to help formulate an understanding of how the universe came into being by examining local events with the distribution of the cosmological data we are accumulating. A Spherical Cow anyone?

I do appreciate all those scientist who have been giving their time to educating the public. This is a big thank you for that devotion to the ideal of bringing society forward as to what we as a public are not privy too. As too, being not part of that 3% of the population who are far removed from the work being done in particle research.

Almost a year ago, I had an e-mail exchange, and planned a phone call, with Maria Spiropulu of CMS. She looked particularly excited about something and the mortals may be learning what the cause was today.

CMS turned out to be much more "aggressive" relatively to the "conservative" ATLAS detector and it has already provided us with some hints. But what they published today, in the paper called: See:
CMS: a very large excess of diphotons

Measurement of the Production Cross Section for Pairs of Isolated Photons in pp collisions at sqrt(s) = 7 TeV
The integrated and differential cross sections for the production of pairs of isolated photons is measured in proton-proton collisions at a centre-of-mass energy of 7 TeV with the CMS detector at the LHC. A data sample corresponding to an integrated luminosity of 36 inverse picobarns is analysed. A next-to-leading-order perturbative QCD calculation is compared to the measurements. A discrepancy is observed for regions of the phase space where the two photons have an azimuthal angle difference, Delta(phi), less than approximately 2.8.

Tscan

Tscan ("Trivial Scanner") is an event display, traditionally called a scanner, which I developed. It is a program that shows events graphically on the computer screen.

It was designed to be simple ("trivial") internally, and to have a simple user interface. A lot of importance was given to giving the user a large choice of options to display events in many different ways.

Tscan proved to be a very useful tool for the development of fitters. A particularly useful feature is the ability to show custom data for every photpmultiplier tube (PMT). Instead of the usual time and charge, it can show expected charge, scattered light, likelihood, chi-squared difference, patches, and any other data that can be prepared in a text format.

Multiple rings of Cerenkov light brighten up this display of an event found in the Super-Kamiokande - neutrino detector in Japan. The pattern of rings - produced when electrically charged particles travel faster through the water in the detector than light does - is similar to the result if a proton had decayed into a positron and a neutral pion. The pion would decay immediately to two gamma-ray photons that would produce fuzzy rings, while the positron would shoot off in the opposite direction to produce a clearer ring. Such kinds of decay have been predicted by "grand unified theories" that link three of nature's fundamental forces - the strong, weak and electromagnetic forces. However, there is so far no evidence for such decays; this event, for example, did not stand up to closer scrutiny.
