On the B $+ A F w - t o J / + A F w - P s i K^{*}$ Decay

Xuan Son Nguyen, Xuan-Yem Pham

We calculate the process- and polarization-dependent nonfactorizable terms $+ A F w - w i d e t i l d e a_{+ A F w - l amb d a}$ of the B $+ A F w - t o$ J $/ + A F w - P s i + A F w - r m K^{*}$ decay within the QCD-impro…

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…

Is the lepton flavour changing observable in $Z \to μ^{\pm} + τ^{\mp}$ decay?

X. Y. Pham

Neutrino oscillations as suggested by the recent Super-Kamiokande result imply that lepton numbers could be violated, and Z $\to μ^{\mp} + τ^{\pm}$ is a typical manifestation. We poi…

CP violation in $η \to π π$ by Higgs - $η$ mixing through two-loop quantum effects

X. Y. Pham

Strictly within the standard electro-weak interaction, CP violation in the flavour conserving process $η\ra π+ π$ could originate from the mixing of the $η$ meson with the virtual…
