Description
We report on measurements of Upsilon mesons in the dielectron channel with the STAR detector at RHIC.
Upsilon mesons are expected to be sensitive to the deconfinement transition in the Quark Gluon Plasma, and
to be useful in determining the medium temperature. We compare the yield obtained in Au+Au data,
separated into three centrality classes, to the measured cross section from p+p collisions. Our data are compared
to models of bottomonium dissociation.
