Abstract
The differential production cross section is measured as functions of the transverse momentum and rapidity in collisions at , using the decay, and compared with predictions based on perturbative QCD calculations at next-to-leading order. The data sample, collected by the CMS experiment at the LHC, corresponds to an integrated luminosity of . The is reconstructed from the decays and . The integrated cross section times branching fraction in the range and is measured to be , where the first uncertainty is statistical and the second is systematic.
