$R_D$ and $R_{D^*}$: Theoretical Development

TL;DR

This paper reviews recent theoretical developments addressing the B anomaly, focusing on discrepancies in $R_D$ and $R_{D^*}$ between experimental results and Standard Model predictions, and discusses potential New Physics explanations.

Contribution

It summarizes new theoretical insights and bounds on New Physics related to the B anomaly presented at CIPANP2018.

Findings

Discrepancies between experimental data and Standard Model predictions for $R_D$ and $R_{D^*}$.

Potential New Physics explanations for the B anomaly.

Additional bounds on New Physics from relevant observables.

Abstract

Recent theoretical developments on $R_D$ and $R_{D^*}$ -- discrepancies between experimental data and the Standard Model predictions have been reported (B anomaly) -- are reviewed. New Physics explanations for the B anomaly and other relevant observables to obtain additional bounds on New Physics are also summarized. This is the proceedings for the talk at CIPANP2018 which was held on May 29 2018.
