Recent Measurements of CP Asymmetries of B \to ϕK^0 and B \to η' K_S at B-factories Suggest New CP Violation in Left-Handed Squark Mixing
Motoi Endo, Satoshi Mishima, Masahiro Yamaguchi
Recent results on the mixing-induced CP asymmetries of B \to ϕK^0 and B \to η' K_S measured at B-factories appear to indicate discrepancies from the Standard Model expectation. Exp…
New Constraint on Squark Flavor Mixing from 199Hg EDM
Motoi Endo
We obtain a new constraint on the CP-violating flavor mixing between the left-handed top scalar quark (\tilde{t}_L) and charm scalar quark (\tilde{c}_L), by considering a chargino…
Measurement of Squark Flavor Mixings in Supersymmetric Models at Super B Factory
Motoi Endo, Satoshi Mishima
We discuss potential to measure squark flavor mixings based on future data at super B factory and LHC. In particular we focus on the imaginary part of the mixings by investigating…
Large Supersymmetric Contribution to CP Asymmetry of B_d \to ϕK_S from Left-Handed Squark Mixing
Motoi Endo, Mitsuru Kakizaki, Masahiro Yamaguchi
Supersymmetric contribution to the CP asymmetry of B_d \to ϕK_S is re-examined. It is emphasized that our analysis takes into account the recently found constraint from the mercury…
