rho(0) photoproduction in AuAu collisions at root s(NN)=62.4 GeV measured with the STAR detector

Original language description

Vector mesons may be photoproduced in relativistic heavy-ion collisions when a virtual photon emitted by one nucleus scatters from the other nucleus, emerging as a vector meson. The STAR Collaboration has previously presented measurements of coherent ?0photoproduction at center of mass energies of 130 GeV and 200 GeV in AuAu collisions. Here, we present a measurement of the cross section at 62.4 GeV; we find that the cross section for coherent ?0 photoproduction with nuclear breakup is 10.5?1.5?1.6 mbat 62.4 GeV. The cross-section ratio between 200 GeV and 62.4 GeV is 4.4 ? 0.6, less than is predicted by most theoretical models.
