Sažetak
The momentum correlation between protons and Lambda 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 Lambda 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.)+0.44 −0.16(syst.) fm.
