Efficacy of scalar leptoquark on $B_s\to (K^{(\ast )},D_s^{(\ast )})\tau {\bar{\nu }}_{\tau }$ decay modes

Suchismita Sahoo, Anupama Bhol

We scrutinize the impact of various relevant scalar leptoquarks on the physical observables associated with the rare semileptonic decay processes of $B_s$ meson involving $b \to (u…
