Theory of Neutrinos

R. N. Mohapatra, S. Antusch, K. S. Babu +29

After a brief overview of the present knowledge of neutrino masses and mixing, we summarize what can be learned about physics beyond the standard model from the various proposed ne…

CP asymmetry, branching ratios and isospin breaking effects of B -> K* gamma with the perturbative QCD approach

M. Matsumori, A. I. Sanda, Y. -Y. Keum

The radiative B -> K* gamma mode is caused by a penguin operator which is a quantum correction. Thus this mode may be useful in the search for physics beyond the standard model. In…

Dynamically enhanced decays in perturbative QCD

Y. -Y. Keum

We investigate the decays, one of hardly understandable processes among charmless B-meson decays, within the perturbative QCD method. Owing to the dynamically enhanc…

Determination of weak phases and from in the pQCD method

Yong-Yeon Keum

We look at two methods to determine the weak phases and from and decays within the perturbative QCD approach. We obtain quite interesting bounds on $ϕ_2…

Direct CP Asymmetry of B -> X_d γin the effective SUSY model

A. G. Akeroyd, Y. -Y. Keum, S. Recksiegel

We investigate the effect of supersymmetric CP violating phases on the inclusive decay B\to X_dγ. Although such a decay contains a large background from B\to X_sγ, if isolated it m…
