Berry Phase in Neutrino Oscillations
Xiao-Gang He, Xue-Qian Li, Bruce H. J. McKellar +1
We study the Berry phase in neutrino oscillations for both Dirac and Majorana neutrinos. In order to have a Berry phase, the neutrino oscillations must occur in a varying medium, t…
Hadron decay amplitudes from and decays
Xiao-Gang He, Bruce McKellar
One can analyze the hadronic decay amplitudes for decays using flavor SU(3) symmetry in different ways, such as the algebraic and quark diagram approaches. We derive spec…
Lepton flavor violating tau and B decays and heavy neutrinos
Xiao-Gang He, G. Valencia, Yili Wang
We study lepton flavor violating (LFV) tau and B decays in models with heavy neutrinos to constrain the mixing matrix parameters U_{tau N}. We find that the best current constraint…
Photoproduction and Radiative Decay of Spin 1/2 and 3/2 Pentaquarks
Xiao-Gang He, Tong Li, Xue-Qian Li +1
We study photoproduction and radiative decays of pentauqarks paying particular attention to the differences between spin-1/2 and spin-3/2, positive and negative parities of pentaqu…
Constraints on New Physics from
N. G. Deshpande, Dilip Kumar Ghosh, Xiao-Gang He
We study constraints on new physics from the recent measurement of Br ( by the E787 and E949 Collaborations. In our analysis we consider two models of new phy…
Parity, Charge Conjugation and SU(3) Constraints on Threshold Enhancement in decays into and
Xiao-Gang He, Xue-Qian Li, J. P. Ma
We study the threshold enhancement effects of baryon-anti-baryon systems in decays at BES using parity , charge conjugation , and flavor SU(3) symmetries. The and $…
