Transverse momentum resummation at small x for the Tevatron and LHC
Authors
Abstract
Analysis of semi-inclusive DIS hadroproduction suggests broadening of transverse momentum distributions at below a few , which can be modeled in the Collins-Soper-Sterman formalism by a modification of impact-parameter-dependent parton densities. We discuss the consequences of such a modification for the production of electroweak bosons at hadron-hadron colliders. If substantial small- broadening is observed in forward Z boson production in the Tevatron Run-2, it will strongly affect predicted transverse momentum distributions for W, Z, and Higgs boson production at the Large Hadron Collider.
