Spin correlations, using a generic spin basis, are investigated to leading order in QCD for top quark production at lepton colliders. Even though, these radiative corrections induce an anomalous Î³/Zâ€¦ (More)

The hadron spin physics is now one of the most active fields. Especially in the last ten years, a lot of progress have been made both theoretically and experimentally which have considerably improvedâ€¦ (More)

Recently, there have been some reports on the long-term clinical outcome of gastric marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue type (MALT lymphoma) [1]. Localized gastric MALTâ€¦ (More)

The lepton helicity distributions in the polarized Drell-Yan process at RHIC energy are investigated. For the events with relatively low invariant mass of lepton pair in which the weak interaction isâ€¦ (More)

We present a systematic study of the B meson light-cone wavefunctions in QCD in the heavy-quark limit. We construct model-independent formulae for the light-cone wavefunctions in terms of independentâ€¦ (More)

We investigate the Sudakov double logarithmic corrections to the form factor of fermion in the SU(2)âŠ—U(1) electroweak theory. We adopt the familiar Feynman gauge and present explicit calculations atâ€¦ (More)

We present QCD prediction of double-spin asymmetries (ATT ) in transversely polarized Drell-Yan process at small transverse momentum QT of dimuon. Resummation of large logarithmic corrections,â€¦ (More)

The GGG and qiG jets in the decay of very,heavy paraquarkonia are analyzed in perturbative quantum chromodynamics. The thrust distributions are calculated and the result is compared with the thrustâ€¦ (More)

We discuss the transverse momentum QT distribution of Drell-Yan pair, produced in collisions of transversely polarized protons. We calculate the transversely polarized Drell-Yan cross section up toâ€¦ (More)

We investigate the nucleon's transverse spin-dependent structure function g2(x;Q ) in the framework of the operator product expansion and the renormalization group. We construct the complete set ofâ€¦ (More)
