Se p 20 04 Effects of R-parity Violation on the Charged Higgs Boson Deacys

We calculate one-loop R-parity-violating couplings corrections to the processes H − → τ ν̄τ and H− → bt̄. We find that the corrections to the H− → τ ν̄τ decay mode are generally about 0.1%, and can be negligible. But the corrections to the H− → bt̄ decay mode can reach a few percent for the favored parameters. PACS number: 14.80.Cp, 14.80.Ly, 12.38.Bx
