TL;DR

This paper calculates semileptonic and nonleptonic decay widths of $B_s$ mesons using constituent quark models, providing detailed predictions for various decay channels.

Contribution

It offers new theoretical predictions for $B_s$ decay widths within the constituent quark model framework, including both semileptonic and nonleptonic processes.

Findings

Decay widths for semileptonic $B_s$ decays to kaons and $D_s$ states calculated.

Nonleptonic decay widths estimated using factorisation approximation.

Results provide benchmarks for future experimental measurements.

Abstract

In this contribution we compute some nonleptonic and semileptonic decay widths of $B_s$ mesons, working in the context of constituent quark models \cite{Albertus:2014gba, Albertus:2014bfa}. For the case of semileptonic decays we consider reactions leading to kaons or different $J^\pi$ $D_s$ mesons. The study of nonleptonic decays has been done in the factorisation approximation and includes the final states enclosed in Table 2.
