|Abstract: ||We study the production of W bosons at large transverse momentum in p¯p collisions.
We show that the next-to-leading order cross section at large transverse momentum is
dominated by threshold soft-gluon corrections. We add next-to-next-to-leading-order softgluon
corrections to the exact next-to-leading-order differential cross sections. We find
that these higher-order corrections provide modest enhancements to the transverse momentum
distribution of the W at the Tevatron, and reduce significantly the dependence
on the factorization and renormalization scales.|
