Transversely Polarized Drell-Yan Process and Soft Gluon Resummation in QCD
Hiroyuki Kawamura, Jiro Kodaira, Kazuhiro Tanaka
We calculate the transverse-momentum spectrum of the dilepton in the transversely polarized Drell-Yan process on the basis of the factorization theorem in QCD. We take into a…
Factorization and Gauge Invariance of Twist-3 Cross Section for Single Spin Asymmetry
Yuji Koike, Kazuhiro Tanaka
We prove factorization and gauge invariance of the twist-3 single-spin-dependent cross section in the leading order perturbative QCD, which was missing in the previous literature.…
Universal Structure of Twist-3 Soft-Gluon-Pole Cross Sections for Single Transverse-Spin Asymmetry
Yuji Koike, Kazuhiro Tanaka
We prove that twist-3 soft-gluon-pole (SGP) cross section for single spin asymmetries (SSA) is determined by a certain ``primordial'' twist-2 cross section up to kinematic and colo…
Soft gluon corrections to double transverse-spin asymmetries for small- dilepton production at RHIC and J-PARC
Hiroyuki Kawamura, Jiro Kodaira, Kazuhiro Tanaka
We calculate the double transverse-spin asymmetries, $\aqt$, in transversely polarized Drell-Yan process at the transverse-momentum of the produced lepton pair. We perform al…
