QCD Prediction of $A_{T T}$ for Small $Q_{T}$ Dimuon Production in $pp$ and $p\bar{p} Collisions

arXiv:hep-ph/0612019 · doi:10.1063/1.2750852

Abstract

We present QCD prediction of double-spin asymmetries ( $A_{T T}$ ) in transversely polarized Drell-Yan process at small transverse momentum $Q_{T}$ of dimuon. Resummation of large logarithmic corrections, relevant in small $Q_{T}$ region, is performed up to next-to-leading logarithmic (NLL) accuracy. $A_{T T}$ at RHIC, J-PARC and GSI are studied numerically in the corresponding kinematic regions.We show that the large $A_{T T}$ is obtained for small $Q_{T}$ and moderate energies.
