New physics in inclusive $B\to X_c\ell \bar{\nu }$ decay in light of $R(D^{(\ast )})$ measurements

Saeed Kamali, Ahmed Rashed, Alakabha Datta

In this work we study the effects of new-physics (NP) operators with different Lorentz structures on the inclusive $B\to X_c\tau \bar{\nu }$ decay and make predictions for the ratio of tot…
