Effects of R-parity Violation on the Charged Higgs Boson Decays
We calculate one-loop R-parity-violating couplings corrections to the processes $H^-\to τ\bar{ν_τ}$ and $H^-\to b\bar{t}$. We find that the corrections to the $H^-\to τ\bar{ν_τ}$ 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.
