This is a simulation of a type of collision we observer at CERN with the NA49 detector. The impact parameter is very small. This shows the partonic epoch in configuration space. Particles are color coded according to qcd color. This shows the partonic epoch in momentum space.
Particles are color coded according to qcd color.
This shows the expansion in configuration space just after the partonic epoch. Particles are color coded according electric charge, baryon, strangeness and open charm contents. This shows the momentum distributions just after the partonic epoch. Particles are color coded according electric charge, baryon, strangeness and open charm contents. This shows the late stages of the expansion in configuration space.
