Investigation of Intrinsic kT and DY processes — •Mikel Mendizabal and Hannes Jung — DESY (Deutsches Elektronen-Synchrotron DESY), Hamburg, Germany
With Parton Branching (PB) we are able to describe the parton evolution in terms of transverse momentum dependent parton density functions (TMDs). We present an application of PB-TMDs to Drell-Yan (DY) production, where the PB-TMDs are matched to MC@NLO matrix element. We compare our predictions to a wide DY mass range (NuSea √s=38.8 GeV, LHC √s=8, 13 TeV), showing a good agreement with measurements. In addition, we study the role of non-perturbative effects in the PB approach at NLO, specifically, the role of the intrinsic, non-perturbative kT distribution.
