Description

We present the effects of new physics operators with different Lorentz structures on the inclusive $B\to X_c\tau \overline{\nu }$ decay and make predictions for the ratio of total decay rates, $R(X_c)$ and some differential observables including the forward-backward asymmetry. We include $\mathcal{O}({\alpha }_s)$ radiative and $1/m_b$ non-perturbative corrections to these observables in the Standard Model (SM). We also present some leptoquark models as explicit examples of new physics effects.
