Scrutinizing new physics of $B_d\to \varphi ({\eta }^{{(}^{\prime })},\pi ,\omega )$ decay modes

Abstract

We inspect the exclusive hadronic decay modes $B_d\to \varphi ({\eta }^{{(}^{\prime })},\pi ,\omega )$, induced by quark level transition as $b\to d$ $(\Delta S=0)$, in vector like down quark model. As these decay modes insist highly suppressed followed by the predicted branching fraction $\mathcal{O}(10^{-9})$ which reflects to scrutinize physics beyond the standard model. We constrain the new parameter space inferred from experimental limits on leptonic $B_d\to \ell \ell (\ell =e,\mu ,\tau )$ and nonleptonic decay modes $B_d\to {\eta }^{\prime }{\pi }^0$ and $B_u\to {\rho }^{-}{\eta }^{\prime }$. We then check the new physics contributions can have significant impact on the prominent observable so called branching ratio of $B_d\to \varphi ({\eta }^{{(}^{\prime })},\pi ,\omega )$ processes.
