Interplay between the $R_{D^{(*)}}$ anomaly and the LHC

The current discrepancy in $R_{D^{(*)}}=BR(\bar{B} \to D^{(*)}τ\barν)/BR(\bar{B}\to D^{(*)} \ell \barν)$ where $\ell=e,\,μ$ may imply a know particle with the mass around the order of TeV. Therefore it is well motivated to test those scenarios at the large hadron collider. Thanks to the size of the discrepancy and the analysis based on the effective field theory, the variety of the possible new physics candidates is limited. We focus on the charged Higgs and leptoquark possibility and discuss the collider physics.
