K1(1270)-K1(1400) Mixing Angle and New-Physics Effects in B to K1 l+ l- Decays
Hisaki Hatanaka, Kwei-Chou Yang
We study semileptonic B meson decays B to K_1(1270) l^+ l^- and K_1(1400) l^+ l^- (l=e, mu, tau), where the strange P-wave mesons, K_1(1270) and K_1(1400), are the mixtures of the…
(Pseudo-) Scalar Operators in the MSSM and B to phi K^*, K eta(') Decays
Hisaki Hatanaka, Kwei-Chou Yang
We study the effect of b to s sbar s scalar/pseudoscalar operators, originating from penguin diagrams of neutral Higgs bosons in the MSSM, in B to K eta(') and B to phi K^* decays.…
Pseudoscalar and Scalar Operators of Higgs-Penguins in the MSSM and B to phi K^*, K eta(') Decays
Hisaki Hatanaka, Kwei-Chou Yang
We study the effect of b to s sbar s scalar/pseudoscalar operators in B to K eta('), phi K^* decays. In the minimal supersymmetric standard model (MSSM), such scalar/pseudoscalar o…
Radiatively Induced Spontaneous Symmetry Breaking by Wilson Line in a Warped Extra Dimension
Hisaki Hatanaka
We investigate the dynamical gauge-Higgs unification in the Randall-Sundrum (RS) space-time. We study the dynamical gauge-Higgs unification in the SU(2) gauge theory with a bulk fe…
Symmetry Breaking/Restoration in a Non-Simply Connected Space-Time
Hisaki Hatanaka, Seiho Matsumoto, Katsuhiko Ohnishi +1
Field theories compactified on non-simply connected spaces, which in general allow to impose twisted boundary conditions, are found to unexpectedly have a rich phase structure. One…
