A closer look at the $R_D$ and $R_{D^*}$ anomalies

Bardhan, Debjyoti, Byakti, Pritibhajan, Ghosh, Diptimoy

Understand

The measurement of $R_D$ ($R_{D^*}$), the ratio of the branching fraction of $\overline{B} \to D \tau \bar{\nu}_\tau (\overline{B} \to D^* \tau \bar{\nu}_\tau)$ to that of $\overline{B} \to D l \bar{\nu}_l (\overline{B} \to D^* l \bar{\nu}_l)$, shows $1.9 \sigma$ $(3.3 \sigma)$ deviation from its Standard Model (SM) prediction.

The combined deviation is at the level of $4 \sigma$ according to the Heavy Flavour Averaging Group (HFAG).
In this paper, we perform an effective field theory analysis (at the dimension-6 level) of these potential New Physics (NP) signals assuming $\rm SU(3)_{C} \times SU(2)_{L} \times U(1)_{Y}$ gauge invariance.
We first show that, in general, $R_D$ and $R_{D^*}$ are theoretically independent observables and hence, their theoretical predictions are not correlated.
