Effects of R-parity Violation on the Charged Higgs Boson Decays

Abstract

We calculate one-loop R-parity-violating couplings corrections to the processes $H^{-}\to \tau \overline{{\nu }_{\tau }}$ and $H^{-}\to b\bar{t}$. We find that the corrections to the $H^{-}\to \tau \overline{{\nu }_{\tau }}$ decay mode are generally about 0.1%, and can be negligible. But the corrections to the $H^{-}\to b\bar{t}$ decay mode can reach a few percent for the favored parameters.
