Precision DIS data and TMD parton distributions

Abstract

General formulations of QCD factorization for hadronic collisions extend the notion of ordinary parton distributions to transverse-momentum dependent (TMD) parton density and parton decay functions. We discuss the use of the recent high-precision deep-inelastic scattering (DIS) measurements for determination of TMD distributions. These are relevant for both low-pT and high-pT physics in hadron collisions. We comment on applications to multi-jet final states associated with electroweak gauge boson production at the LHC.
