Detailed analysis of possible new-physics effects in the semileptonic decay $B_s\to D_s^{(\ast )}\tau \bar{\nu }$

Mikhail A. Ivanov, Jignesh N. Pandya, Pietro Santorelli +4

We study the semileptonic decays $B_s\to D_s^{(\ast )}\tau \bar{\nu }$ as a promising probe for new physics (NP) beyond the standard model (SM). The extension of the SM is done through the int…
