We deduce approximate equations of state from experimental measurements in pp and collisions. Thermodynamic quantities are estimated combining the measure of average transverse momentum vs pseudorapidity density with the estimation of the interaction region size from measures of Bose Einstein correlation, or from a theoretical model which relates to the impact parameter. The results are very similar to theory predictions in case of crossover from hadron gas to quark gluon plasma. According to our analysis, the possible crossover should start at dNch/deta about 6 and end at dNch/deta about 24.

Abstract
We deduce approximate equations of state from experimental measurements in pp and collisions. Thermodynamic quantities are estimated combining the measure of average transverse momentum vs pseudorapidity density with the estimation of the interaction region size from measures of Bose Einstein correlation, or from a theoretical model which relates to the impact parameter. The results are very similar to theory predictions in case of crossover from hadron gas to quark gluon plasma. According to our analysis, the possible crossover should start at dNch/deta about 6 and end at dNch/deta about 24.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
