Electroweak boson production at large transverse momentum in double polarized pp scattering at next-to-leading order accuracy

Abstract

We compute the next-to-leading order corrections to the cross section for the production of electroweak gauge bosons (Z, W± and γ∗) with large transverse momentum in double (longitudinally) polarized hadronic collisions. The calculation is fully performed in the 't Hooft, Veltman, Breitenlohner, and Maison scheme within dimensional regularization with a careful treatment of issues arising due to the appearance of γ5 in polarization projectors and axial couplings. We study the phenomenological consequences of the next-to-leading-order corrections at the level of both the double polarized cross section and the corresponding asymmetries at Relativist Heavy Ion Collider kinematics.
