Supersymmetry through CP violation in $H^\pm \to W^\pm h^0$

Abstract

The CP violating asymmetry between the partial decay rates of $H^+ \to W^+ h^0$ and $H^- \to W^- h^0$ is calculated at one-loop level in MSSM with complex parameters. The dependence on the phases of $A_τ$ and $M_1$ is discussed. Different values of $\tan β$ are considered. The asymmetry is up to the order of $10^{-2} $.

12 pages, 3 figures, require JHEP style. In the new version the scolor quark radiative corrections are considered, the numerical results (Figs. 2, 3) are corrected and some minor changes in the notations are made
