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

Hiroyuki Kawamura, Jiro Kodaira, Kazuhiro Tanaka

We present QCD prediction of double-spin asymmetries ($A_{TT}$) in transversely polarized Drell-Yan process at small transverse momentum $Q_T$ of dimuon. Resummation of large logar…
