Two particle rapidity, transverse momentum, and azimuthal correlations in relativistic nuclear collisions and transverse radial expansion

At the very first stage of an ultra-relativistic nucleus-nucleus collision new particles are produced in individual nucleon-nucleon collisions. In the transverse plane, all particles from a single NN collision are initially located at the same position. The subsequent transverse radial expansion of the system creates strong position-momentum correlations and leads to characteristic rapidity, tr...

Hadronic centrality dependence in nuclear collisions

The kaon number density in nucleus+nucleus and p+p reactions is investigated for the first time as a function of the initial energy density ǫ and is found to exhibit a discontinuity around ǫ=1.3 GeV/fm. This suggests a higher degree of chemical equilibrium for ǫ > 1.3 GeV/fm. It can also be interpreted as reflection of the same discontinuity, appearing in the chemical freeze out temperature (T)...
