Transverse double-spin asymmetries for small $Q_T$ Drell-Yan pair production in $pp$ and $p\bar{p}$ collisions

Abstract

We discuss transverse double-spin asymmetries for dimuon production at small transverse-momentum $Q_T$ in $pp$ and $p\bar{p}$ collisions. All order resummation of large logarithms relevant in small $Q_T$ region is performed at next-to-leading logarithmic (NLL) accuracy, and asymmetries at RHIC, J-PARC and GSI are calculated.
