Sudakov Logarithm Resummation for Vector Boson Production at Hadron Colliders
arXiv:hep-ph/9912300 · doi:10.1088/0954-3899/26/5/319
Abstract
A complete description of W and Z boson production at high-energy colliders requires the resummation of large Sudakov logarithms which dominate the production at small transverse momentum. Currently there are two techniques for performing this resummation: impact parameter space and transverse momentum space. We argue that the latter can be formulated in a way which retains the advantages of the former, while at the same time allowing a smooth transition to finite order dominance at high transverse momentum.
