One-loop flavor changing electromagnetic transitions
Q. Ho-Kim, X. Y. Pham
We discuss the effect of the external fermion masses in the flavor-changing radiative transitions of a heavy fermion (quark or lepton) to a lighter fermion at the one-loop level, a…
CP Asymmetries in B_d \to D^{*+}D^{*-} and B_s \to D^{*+}_s D^{*-}_s Decays: P-wave Dilution, Penguin and Rescattering Effects
Xuan-Yem Pham, Zhi-zhong Xing
Determination of the CP-violating parameters \sin 2βand \sin 2β' is shown to be possible from B^0_d vs \bar{B}^0_d \to D^{*+}D^{*-} and B^0_s vs \bar{B}^0_s \to D^{*+}_sD^{*-}_s de…
Massive Neutrino Decays
X. Y. Pham
Neutrino physics is used as an illustrative example for an elementary introduction to the computational method of Feynman loop-diagrams and decay rates. If the neutrinos are as mas…
The decays "neutrino{heavy} -> neutrino{light} + photon" and "neutrino{heavy} -> neutrino{light} e+ e-" of massive neutrinos
Q. Ho-Kim, B. Machet, X. Y. Pham
If, as recently reported by the Super-Kamiokande collaboration, the neutrinos are massive, the heaviest one would not be stable and, though chargeless, could in particular decay in…
