Generalized structure of hadron-quark vertex function in Bethe-Salpeter framework: Applications to leptonic decays of V-mesons
Shashank Bhatnagar, Shi-Yuan Li
We employ the framework of Bethe-Salpeter equation under Covariant Instantaneous Ansatz (CIA) to study the leptonic decays of vector mesons. The structure of hadron-quark vertex fu…
Anti-Lambda polarization in high energy pp collisions with polarized beam
Qing-hua Xu, Zuo-tang Liang, Ernst Sichtermann
We study the polarization of the anti-Lambda particle in polarized high energy pp collisions at large transverse momenta. The anti-Lambda polarization is found to be sensitive to t…
Mixed QCD and Weak Corrections to Production by Quark-Antiquark Annihilation
W. Bernreuther, M. Fuecker, Z. G. Si
We report on our computation of the mixed QCD and weak corrections to including spin effects, in particular on single top spin asymmetries.
Mixed QCD and weak corrections to top quark pair production at hadron colliders
W. Bernreuther, M. Fuecker, Z. G. Si
The order mixed QCD and weak corrections to top quark pair production by quark antiquark annihilation are computed, keeping the full dependence on the and sp…
Spin transfer and polarization of antihyperons in lepton induced reactions
Hui Dong, Jian Zhou, Zuo-tang Liang
We study the polarization of antihyperon in lepton induced reactions such as and with polarized beams using different models for spin trans…
NRQCD Factorization and Universality of NRQCD Matrix Elements
J. P. Ma, Z. G. Si
The approach of nonrelativistic QCD(NRQCD) factorization was proposed to study inclusive production of a quarkonium. It is widely used and successful. However, a recent study of gl…
