We examine the charmless hadronic B decay modes in the context of R-parity violating ($\rpv$) supersymmetry. We try to explain the large branching ratio (compared to the Standard Model (SM) prediction) of the decay $B^{\pm}\to \eta'…
The branching ratios for the neutral and charged B decay channels to $\eta' K$ and $\eta K^*$ are well above the Standard Model expectations. Moreover, the mixing-induced CP asymmetry in $B \to \phi K_S$ is incompatible to that found in…
We study the branching ratios, the direct CP asymmetries in $B\to K^{(*)}\bar{K}^{(*)}$ decays and the polarization fractions of $B\to K^{*}\bar{K}^{*}$ decays by employing the QCD factorization in the minimal supersymmetric standard model…
In the framework of R-parity violating (\rpv) supersymmetry, we try to find a consistent explanation for both recently measured CP asymmetry in B^0 --> phi K_S decay and the large branching ratio of B^{+/-} --> eta' K^{+/-} decay, which are…
We present a complete study of R-parity violating supersymmetric effects in thirteen exclusive and inclusive semi-leptonic $b \to (s,d) \nu \bar{\nu}$ decays, including $B^+_u\to K^{(*)+}\nu\bar{\nu}$, $B^0_d\to K^{(*)0}\nu\bar{\nu}$,…
We present a possible supersymmetric solution to the discrepancy between the observed mixing CP asymmetries in B -> \phi K_S and B -> \eta' K_S. We show that due to the different parity in the final states of these processes, their…
We report measurements of branching fractions and CP asymmetries for $B \to \eta K^*$ and $B \to \eta \rho$ decays. These results are obtained from a $414 {\rm fb}^{-1}$ data sample collected at the $\Upsilon(4S)$ resonance with the Belle…
The nonet symmetry scheme seems to describe rather well the masses and $\eta-\eta^{\prime}$ mixing angle of the ground state pseudo-scalar mesons and is thus expected to be also a good approximation for the matrix elements of the…

We study $B$ physics phenomenology in the scenario of split supersymmetry without R-parity. By assuming the constraints of bilinear (trilinear) R-parity violating couplings, which are introduced to solve the problem of the atmospheric…
In the framework of perturbative QCD approach, we calculate the branching ratio and CP asymmetry for $B_{s}^0(\bar{B}_{s}) \to \pi^{\pm} K^\mp$ and $B_{s}(\bar{B}_{s})\to \pi^{0}\bar{K}^{0}(K^{0})$ decays. Besides the usual factorizable…
In this paper, we calculate the branching ratios and CP-violating asymmetries for $B_{s}\to \rho^\pm K^\mp$, $B_{s}\to\rho^{0}\bar{K}^0 $ and $B_{s}\to\omega\bar{K}^0$ decays in the perturbative QCD (pQCD) factorization approach. The…
Motivated by recent $R_D$, $R_{D^*}$ and $R_{J/\psi}$ anomalies in $B\to D\ell^- \bar{\nu}_{\ell}$, $B\to D^*\ell^- \bar{\nu}_{\ell}$ and $B_c\to J/\psi\ell^- \bar{\nu}_{\ell}$ decays, respectively, we study possible R-parity violating…

The nonet symmetry scheme seems to describe rather well the masses and $\eta-\eta^{\prime}$ mixing angle of the ground state pseudo-scalar mesons. It is expected that nonet symmetry should also be valid for the matrix elements of the…
