Drell-Yan double-spin asymmetry A_{LT} in polarized p\bar{p} collisions: Wandzura-Wilczek contribution
Yuji Koike, Kazuhiro Tanaka, Shinsuke Yoshida
The longitudinal-transverse spin asymmetry A_{LT} in the polarized Drell-Yan process depends on the twist-3 spin-dependent distributions of nucleon. In addition to the contribution…
Double-spin asymmetries for small-Q_T Drell-Yan pair production in transversely polarized p\bar{p} collisions
Hiroyuki Kawamura, Jiro Kodaira, Kazuhiro Tanaka
We discuss the Drell-Yan process at a measured transverse-momentum of the produced lepton pair in collisions of transversely polarized protons and antiprotons, to be observed…
Soft gluon resummation in Drell-Yan dilepton production at small transverse momentum: spin asymmetry and a novel asymptotic formula
Hiroyuki Kawamura, Jiro Kodaira, Kazuhiro Tanaka
We discuss the double-spin asymmetry \aqt in the transversely polarized Drell-Yan process at small transverse-momentum Q_T of the produced dilepton. The soft gluon corrections rele…
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…
