Abstract

The two-proton correlation function at midrapidity from Pb + Pb central collisions at 158 A GeV has been measured by the NA49 experiment. The resultsare 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.
