We analyze the $B\to K_2^*(\to K\pi)l^+l^-$ (with $l=e,\mu,\tau$) decay in the standard model and two new physics scenarios: vector-like quark model and family non-universal $Z'$ model. We derive its differential angular distributions, using the recently calculated form factors in the perturbative QCD approach. Branching ratios, polarizations, forward-backward asymmetries and transversity...

We show that simultaneout precision measurements of the CP-violating phase in time-dependent B_{s} --> J/ψφ study and the B_{s} --> μ+μ- rate, together with measuring m_{t`} by direct search at the LHC, would determine V_{t`b}V*_{t`s} and therefore the quadrangle in the four-generation standard model. The forward-backward asymmetry in B --> K*μ+μ- provides further discrimination.

Due to the smallness of the lepton Yukawa couplings, higher-dimensional operators can give a significant contribution to the lepton masses. In this case, the lepton mass matrix and the matrix of lepton-Higgs couplings are misaligned leading to lepton flavor violation (LFV) mediated by the Standard Model Higgs boson. We derive model-independent bounds on the Higgs flavor violating couplings...

The like-sign dimuon charge asymmetry observed by the D$\O$ Collaboration indicates the CP violating contribution from new physics in the $B_s$ meson mixing. Recently, the LHCb reported the observed CP-violating asymmetry in $B_s^0\to J/\psi \phi$ and $B_s^0\to J/\psi f_0(980) $, which is consistent with the SM prediction. However, there is still possible contribution on the CP violating new...

We discuss the dynamical mass generation resulting from
supersymmetric extensions of the classical Nambu-Jona-Lasinio model namely from
interaction terms with four chiral superfields. The kind of interactions maybe considered a supersymmetric generalization of the four-fermion interactions of the classic Nambu-Jona-Lasinio model. We illustrate the dynamical generation of superfield...
