What Does the Higgs Jet Energy Sound Like?

Top quark and anti top quark pair decaying into jets, visible as collimated collections of particle tracks, and other fermions in the CDF detector at Tevatron.
HiggsJetEnergyProfileCrotale  and HiggsJetEnergyProfilePiano use only the energy of the cells in the jet to modulate the pitch, volume, duration and spatial position of each note. The sounds being modulated in these examples are crotales (baby cymbals) and a piano string struck with a soft beater, then shifted up in pitch by 1000 Hz and `dovetailed'.

In HiggsJetRythSig we are simply travelling steadily along the axis of the jet of particles and hearing a ping of crotales for each point at which there is a significant energy deposit somewhere in the jet.

HiggsJetEnergyGate  uses just the energy deposited in the jet's cells. At each time point (defined by the distance from the point of collision) the energy is used to define the number of channels used from the piano sound file. So high energy can be heard as thick, burbly sound whilst low energy has a thinner sound. See: Listen to the decay of a god particle
