$B_{c}$ ${\to}$ $BP$, $BV$ decays with the QCD factorization approach

TL;DR

This paper analyzes nonleptonic $B_c$ decays into $BP$ and $BV$ final states using QCD factorization, identifying promising decay channels with sizable branching ratios for experimental observation.

Contribution

It applies the QCD factorization approach to $B_c$ decays, providing predictions for branching ratios of various decay channels, highlighting those most likely to be observed.

Findings

Cabibbo favored decays $B_c \to B_s \pi, B_s \rho, B_u \bar{K}$ have branching ratios > 1%

These decay channels are promising for early detection by LHCb

The study offers theoretical predictions for experimental verification

Abstract

We studied the nonleptonic $B_{c}$ ${\to}$ $BP$, $BV$ decay with the QCD factorization approach. It is found that the Cabibbo favored processes of $B_{c}$ ${\to}$ $B_{s}{\pi}$, $B_{s}{\rho}$, $B_{u}\bar{K}$ are the promising decay channels with branching ratio larger than 1\%, which should be observed earlier by the LHCb Collaboration.
