Transverse Momentum Dependent (TMD) parton distributions obtained from the Parton Branching (PB) method are combined with next-to-leading-order (NLO) calculations of Drell-Yan (DY) production. We apply the MC@NLO method for the hard process calculation and matching with the PB TMDs.
We compute predictions for the transverse momentum of Z bosons and Drell-Yan (DY) production. The theoretical predictions agree well, within uncertainties, with measurements at the Large Hadron Collider (LHC). We also compute the transverse momentum spectrum of low mass DY production at low center-of-mass energies and compare our predictions with experimental measurements at low DY mass, and find very good agreement. In addition we use the low mass DY measurements at low to determine the width of the intrinsic Gauss distribution of the PB -TMDs at low evolution scales and find values that have earlier been used in applications of PB -TMDs to high-energy processes at the LHC and HERA.
