On the Observation of Top Spin Correlation Effect at Tevatron
Darwin Chang, Shih-Chang Lee, Alexei Soumarokov
We propose to observe the top spin correlation effect at Tevatron through the measurement of the correlated asymmetries of the charged lepton momenta using the dilepton decay event…
Quark Confinement in Light-Front QCD and A Weak-Coupling Treatment to Heavy hadrons
Wei-Min Zhang
In this paper, we develop a weak-coupling treatment of nonperturbative QCD to heavy hadrons on the light-front. First, we present a derivation of quark confining interaction in lig…
Polarized Parton Distribution Functions Reexamined
Hai-Yang Cheng, Hung Hsiang Liu, Chung-Yi Wu
The hard-gluonic contribution to the first moment of the polarized proton structure function is dependent of the factorization convention chosen in defining the quark sp…
Probing u-bar/d-bar Asymmetry in the Proton via Quarkonium Production
J. C. Peng, D. M. Jansen, Y. C. Chen
The sensitivity of proton-induced and production to the possible asymmetry in the nucleon is studied. The ratio of the quarkonium production cross section…
Analysis of Two-Body Decays of Charmed Baryons Using the Quark-Diagram Scheme
Ling-Lie Chau, Hai-Yang Cheng, B. Tseng
We give a general formulation of the quark-diagram scheme for the nonleptonic weak decays of baryons. We apply it to all the decays of the antitriplet and sextet charmed baryons an…
Implications on two Higgs doublet models from the latest measurement and top discovery
Chao-Hsi Chang, Caidian Lü
The constraints on the two Higgs doublet model from the new experimental bounds of by CLEO and the latest published value of the top quark mass by CDF and D0 are reanalyz…
