The Dilepton Q_T Spectrum in Transversely Polarized Drell-Yan Process in QCD
Hiroyuki Kawamura, Jiro Kodaira, Hirotaka Shimizu +1
We discuss the transverse momentum Q_T distribution of Drell-Yan pair, produced in collisions of transversely polarized protons. We calculate the transversely polarized Drell-Yan c…
Unraveling Soft Components in the Shape Function for Inclusive B Decays
Hiroyuki Kawamura, Jiro Kodaira, Kazuhiro Tanaka
We present a systematic study of the shape function for inclusive B-meson decays in the heavy-quark limit, which is based on the QCD equations of motion and heavy-quark symmetry, a…
Q_T Resummation in Transversely Polarized Drell-Yan Process
H. Kawamura, J. Kodaira, H. Shimizu +1
We calculate QCD corrections to transversely polarized Drell-Yan process at a measured of the produced lepton pair in the dimensional regularization scheme. The distrib…
Self-consistent relativistic random phase approximation with vacuum polarization
A. Haga, H. Toki, S. Tamenaga +2
We present a theoretical formulation for the description of nuclear excitations within the framework of relativistic random-phase approximation whereby the vacuum polarization aris…
