Y cross section in p+p collisions at STAR

The main focus of the heavy flavour programme at RHIC is to investigate the properties of the dense matter produced in heavy-ion collisions by studying its effect on open heavy flavour and quarkonia production. This in turn requires a detailed understanding of their production in elementary p+p collisions so that the dense matter effects can be later unfolded. In this paper, we present the first midrapidity cross section measurement of bottomonium at √S = 200 GeV with the STAR experiment. We compare our results with perturbative QCD calculations. A brief status on the study of charmonium in STAR is given.
