| Abstract: | The momentum correlation between protons and Λ [lambda] particles emitted from central Pb+Pb collisions at √sNN=17.3 [square root of s subscript NN = 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 [q subscript inv <0.2] GeV). By fitting a theoretical model, which uses the strong interaction between the proton and the Λ [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.)-0.16+0.44(syst.) [RG = 3.02±0.20 (stat.) subscript -0.16 superscript +0.44 (syst.)] fm. |
