Description
Correlations between non-identical particles at small relative
velocity probe asymmetries in the average space-time emission points at
freezeout. Such asymmetries may arise from long-lived resonances, bulk
collective effects, or differences in the freezeout scenario for the
different particle species. STAR has extracted pion-proton correlation
functions from a high-statistics dataset of Au+Au collisions at
$\sqrt{s_{NN}}=200GeV$. We present femtoscopic analysis using
spherical-harmonics decomposition of this data for
pions and protons, for collisions of different centrality.
Preliminary quantitative results extracted from this data are
presented for the first time.
