Two-proton correlations from 158 A GeV Pb+Pb central collisions

Αγγλικά

The two-proton correlation function at midrapidity from Pb + Pb central
collisions at 158 A GeV has been measured by the NA49 experiment. The
results are compared to model predictions from static thermal Gaussian
proton source distributions and transport models rqmd and venus. An
effective proton source size is determined by minimizing chi(2)/ndf
between the correlation functions of the data and those calculated for
the Gaussian sources, yielding sigma(eff) = 3.85 +/-
0.15(stat.)(-0.25)(+0.60)(syst.) fm. Both the rqmd and the venus model
are consistent with the data within the error in the correlation peak
region. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
