Abstract
production in collisions at has been measured by the PHENIX experiment at the BNL Relativistic Heavy Ion Collider over a rapidity range of and a transverse momentum range of . The size of the present data set allows a detailed measurement of both the and the rapidity distributions and is sufficient to constrain production models. The total cross section times the branching ratio is .
