Towards a unified explanation of $R_{D^{(\ast )}}$, $R_K$ and $(g-2{)}_{\mu }$ anomalies in a left-right model with leptoquarks

We present a unified explanation for the $B$-decay anomalies in $R_{D^{(\ast )}}$ and $R_K$ together with the anomalous muon magnetic moment, consistent with the constraints from the current measurements of leptonic decay rates and $D^0-{\bar{D}}^0$, $B_s^0-{\bar{B}}_s^0$ mixings, within the framework of a minimal left-right symmetric gauge theory motivated by one of the low-energy subgroups of $E_6$ naturally accommodating leptoquarks.
