Charged Higgs bosons from the 3-3-1 models and the $\mathcal{R}(D^{(*)})$ anomalies

Several anomalies in the semileptonic B-meson decays such as R(D(*)) have been reported by the BABAR, Belle, and LHCb collaborations recently. In this paper, we investigate the contributions of the charged Higgs bosons from the 3-3-1 models to the R(D(*)) anomalies. We find that, in a wide range of parameter space, the 3-3-1 models might give reasonable explanations to the R(D(*)) anomalies and other analogous anomalies of the B meson’s semileptonic decays.
