Abstract: One loop mediated charged Higgs bosons decays $H^\pm\to W^\pm V$, $V= Z,\gamma$ are studied in the Minimal Supersymmetric Standard Model MSSM withand without CP violating phases. We evaluate the MSSM contributions to theseprocesses taking into account $B\to X s\gamma$ constraint as well asexperimental constraints on the MSSM parameters. In the MSSM, we found that inthe intermediate range of $\tan\beta \la 10$ and for largeA t and large $\mu$, where the lightest top squark becomes very light andhence non-decoupled, the branching ratio of $H^\pm \to W^{\pm} Z$ can be of theorder 10^{-3} while the branching ratio of $H^\pm \to W^{\pm} \gamma$ is of theorder 10^{-5}. We found also that the CP violating phases of soft SUSYparameters can modify the branching ratio by about one order of magnitude. Wealso show that MSSM with CP violating phases lead to CP-violating asymmetry inthe decays $H^+ \to W^+V$ and $H^- \to W^-V$. Such CP asymmetry can be ratherlarge and can reach 80% in some region of parameter space.
