New-physics contributions to the forward-backward asymmetry in B -> K* mu+ mu-

Ashutosh Kumar Alok, Amol Dighe, Diptimoy Ghosh +4

We study the forward-backward asymmetry (AFB) and the differential branching ratio (DBR) in B -> K* mu+ mu- in the presence of new physics (NP) with different Lorentz structures. W…

New Physics in Bs -> J/psi phi: a General Analysis

Cheng-Wei Chiang, Alakabha Datta, Murugeswaran Duraisamy +3

Recently, the CDF and D0 collaborations measured indirect CP violation in Bs -> J/psi phi and found a hint of a signal. If taken at face value, this can be interpreted as a nonzero…

CP Violation in Three-Body Chargino Decays

Makiko Nagashima, Ken Kiers, Alejandro Szynkman +3

CP violation in supersymmetry can give rise to rate asymmetries in the decays of supersymmetric particles. In this work we compute the rate asymmetries for the three-body chargino…

CP violation in tau -> K pi pi nu_tau

Ken Kiers, Kevin Little, Alakabha Datta +3

We consider CP-violating effects in tau->K pi pi nu_tau, assuming that a charged Higgs boson provides a new amplitude that can interfere with the usual Standard Model amplitude. We…

U-spin Implication for B_s Physics and New Physics

Makiko Nagashima

With U-spin symmetry, b->s and b->d penguin decays could be a subtle probe of CP violating new physics contributions. We show that, for B->PP (P stands for a pseudoscalar meson), t…

Final-state Polarization in Bs Decays

Alakabha Datta, David London, Joaquim Matias +2

Certain Bs --> V_1V_2 decays (V_i is a vector meson) can be related by flavor SU(3) symmetry to corresponding Bd --> V_3V_4 decays. In this paper, we show that the final-state pola…
