Possibility of Large EW Penguin contribution
Satoshi Mishima, Tadashi Yoshikawa
We discuss a possibility of large electroweak(EW) penguin contribution in B-->K pi and pi pi. The recent experimental data may be still suggesting that there are some discrepancies…
Search for New Physics in B Decays
A. I. Sanda, T. Yoshikawa
We review recent important progresses at the B factories and discuss the future prospects. We also comment on how we might proceed to search for new physics.
B-> X_sl^+l^- and B->Kπdecays in vectorlike quark model
T. Morozumi, Z. Xiong, T. Yoshikawa
In the framework of SU(2) singlet down type vectorlike quark model, we present a comprehensive analysis for decays B-> X_s γ, B->X_sl^+l^- and B-> Kπ. As for B-> X_sγ, we include t…
Large electroweak penguin contribution in B --> K pi modes
Tadashi Yoshikawa
I discuss about a possibility of large electroweak penguin contribution in B --> K pi. To satisfy several relations among the branching ratios, we need large electroweak penguin co…
