Decays $B\to {\eta }^{\prime }K$ in R-parity violating supersymmetry

Abstract

In light of the recent experimental data from $B$ factories, We try to explain the large branching ratio (compared to the Standard Model prediction) of the decay $B^{\pm }\to {\eta }^{\prime }{K}^{\pm }$ in the context of R-parity violating ($\text{rpv}$) supersymmetry. We investigate other observed ${\eta }^{(\prime )}$ modes and find that only two pairs of $\text{rpv}$ coupling can satisfy the requirements without affecting the other $B\to PP$ and $B\to VP$ decay modes except the mode $B\to \varphi K$. We also calculate the CP asymmetry for the observed decay modes affected by the new couplings.
