Effects of QCD Resummation on Distributions of Leptons from the Decay of Electroweak Vector Bosons
Csaba Balazs, Jianwei Qiu, C. --P. Yuan
Abstract
We study the distributions of leptons from the decay of electroweak vector bosons produced in hadron collisions. The effects of the initial state multiple soft-gluon emission, using the Collins--Soper resummation formalism, are included. The resummed results are compared with the next-to-leading-order results for the distributions of the transverse momentum, rapidity asymmetry, and azimuthal angle of the decay leptons.
