High transverse mass pion and proton correlations in central Pb Pb collisions at $\sqrt{S_{NN}}$ = 17GeV/nucleon
For central Pb Pb collisions at a center of mass energy of $\sqrt{S_{NN}}$ = 17.3 GeV/nucleon we have made the first two-dimensional measurement of the pp correlation function. These data extend the range of previous studies of HBT radii by a factor of two in transverse mass. They are consistent wit...

| description | For central Pb Pb collisions at a center of mass energy of $\sqrt{S_{NN}}$ = 17.3 GeV/nucleon we have made the first two-dimensional measurement of the pp correlation function. These data extend the range of previous studies of HBT radii by a factor of two in transverse mass. They are consistent with a hydrodynamic interpretation and microscopic models that include hadronic rescattering and transverse expansion. We also report new data on pion correlations. The two particle correlations of negative pions at a transverse mass of 0.92 GeV imply source radii that are smaller than typical hydrodynamic fits and transport model simulations. It is possible that these fast pions may have left the source before the build up of hydrodynamic flow. |
