CP violation in Supesymmetry and the LHC

In this talk I discuss possibilities of probing the CP violation (CPV) in the Minimal Supersymmetric Standard Model (MSSM), at the LHC as well as its effects on the LHC SUSY phenomenology. In the latter case I mainly discuss its effect on the Higgs-sector and hence on Higgs Phenomenology at the LHC. After outlining the possibilities that a study of the ${\mathrm{ch}}_1{\text{nt}}_2$ production at the LHC might offer, I will summarise the effects of the CPV in MSSM on the Higgs searches at the LHC. Further, I will discuss how a study of the process $H^\pm \to W^+ \phi_1$maybeabletoplug{a}^{\mathrm{\prime }}hole\mathrm{"}inthe$\tan \beta$-$\mh{+}$ plane, where the LEP has no sensitivity and where the searches in the usual discovery channels at the LHC are likely to fail as well.
