The two-proton correlation function at midrapidity from Pb+Pb central collisions at 158 AGeV 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-square/ndf between the correlation functions of the data and those calculated for the Gaussian sources, yielding 3.85 +-0.15(stat.) +0.60-0.25(syst.) fm. Both the RQMD and the VENUS model are consistent with the data within the error in the correlation peak region.

The two proton correlation function was analysed using proton from the rapidity range YRAP = 2.4 to 2.9 in the TOF analysis, and 2.9 to 3.4 in the dE/dx analysis. Momentum magnitude of the proton in the rest frame of the pair. All quoted errors are statistical only. (C=CORRECTED) relates to correlation function corrected for 44% contamination in the proton pair sample due to weak decay protons. (C=UNCORRECTED) means uncorrected correlation function.

Measurements of the partial linear momentum transfer and production cross sections for light charged particles are reported for the reaction 680 MeV Ar40+natAg. From examination of light charged particle invariant cross section maps and comparison of experimental angular distributions and energy spectra to a reaction kinematics simulation, an average value of 85% linear momentum transfer is deduced, with a spin range of (0–75)ħ. Integration over energy and angle yields single and coincident light charged particle production cross sections. © 1996 The American Physical Society.

SMALL ANGLE CORRELATIONS OF IDENTICAL PARTICLES IN CARBON CARBON INTERACTIONS AT P = 4.2-GEV/C PER NUCLEON

Two-particle small-angle correlations between negative pions and between protons in carbon-carbon collisions atP=4.2 GeV/c per nucleon have been studied, both for an unbiased sample and for “central” events. A comparison of experimental π− π− andpp correlation functions with theoretical predictions has been made. A possible evidence for the existence of two fireballs in C+C interactions atP=4.2 GeV/c per nucleon is presented.
