Resolving the B-> phi K^* Polarization Anomaly

Wei-Shu Hou, Makiko Nagashima

The experimental observation of sizable transverse components for B-> phi K^* decay is in strong contrast to all other VV modes, and poses a challenge to our understanding of B dec…

Mixing Matrix of Quarks Having Natural Twisting in E_6 Grand Unified Model

Midori Obara, Gi-Chol Cho, Makiko Nagashima +1

Mass matrix of quarks is studied in the Supersymmetric $E_{6}$ Grand Unified Theory (GUT). The fundamental representation $27$ in $E_{6}$ which corresponds to one generation c…

Contributions of Vector-Like Quarks to $B \to X_{s} γ$ and $B_{s}^{0} B ˉ_{s}^{0}$ Mixing

Mayumi Aoki, Makiko Nagashima, Noriyuki Oshimo

The radiative decay $\BSgamma$ and the mixing $\BsBs$ are discussed in the vector-like quark model which contains extra SU(2)-singlet quarks with the same electric charges as the u…
