Abstract
The momentum correlation between protons and Λ particles emitted from central Pb+Pb collisions at √sNN=17.3 GeV was studied by the NA49 experiment at the CERN Super Proton Synchrotron. A clear enhancement is observed for small relative momenta (qinv<0.2 GeV). By fitting a theoretical model, which uses the strong interaction between the proton and the Λ in a given pair, to the measured data, a value for the effective source size is deduced. Assuming a static Gaussian source distribution, we derive an effective radius parameter of RG=3.02±0.20(stat.)-0.16+0. 44(syst.) fm.
