Signatures of the handbag mechanism in wide-angle photoproduction of pseudoscalar mesons
H. W. Huang, R. Jakob, P. Kroll +1
Wide-angle photoproduction of pseudoscalar mesons is investigated under the assumption of dominance of the handbag mechanism considering both quark helicity flip and non-flip. The…
Large momentum transfer electroproduction of mesons
H. W. Huang, P. Kroll
Assuming the proton's light-cone wave function to be dominated by small parton virtualities and small intrinsic transverse momenta, we show that the electroproduction amplitudes at…
QCD predictions for annihilation decays of P-wave quarkonia to next-to-leading order in
Han-Wen Huang, Kuang-Ta Chao
The decay rates of P-wave heavy quarkonia to light hadrons are presented to leading order in and next-to-leading order in . They include contributions from both the colo…
Possible retardation effects of quark confinement on the meson spectrum
Cong-feng Qiao, Han-Wen Huang, Kuang-Ta Chao
The reduced Bethe-Salpeter equation with scalar confinement and vector gluon exchange is applied to quark-antiquark bound states. The so called intrinsic flaw of Salpeter equation…
Electromagnetic Annihilation Rates of and with Both Relativistic and QCD Radiative Corrections
Han-Wen Huang, Cong-Feng Qiao, Kuang-Ta Chao
We estimate the electromagnetic decay rates of and by taking into account both relativistic and QCD radiative corrections. The decay ra…
QCD Radiative Correction to the Hadronic Annihilation Rate of Heavy Quarkonium
Han-Wen Huang, Kuang-Ta Chao
Hadronic annihilation rate of heavy quarkonium is given to next-to-leading order in and leading order in using a recently developed factorization formalism whi…
