Transverse momentum spectrum of Drell Yan pairs — •Heng Yang, Melanie Schmitz, and Hannes Jung — DESY CMS Group, Hamburg, Germany

We apply the Parton Branching method to calculate transverse momentum dependent (TMD) parton densities and fit the free paramters to HERA DIS measurements. These TMD densities are used to calcuate the Drell Yan transverse momentum spectrum for Z bosons at the LHC at next-to-leading order. We apply the same calcualtions to Drell Yan production at lower energies and low mass and estimate the contributin of primordial kt (intrinsic kt).
