Abstract. In this talk I discuss some aspects of CP violation (CPV)

in supersymmetry (SUSY) as well as in the Higgs sector. Further,

I discuss ways in which these  may be probed at hadronic colliders.

In particular I will point out the ways in which  studies in the

$\tilde \chi^\pm, \tilde\chi_2^0$ sector at the Tevatron  may be used

to provide information on this and how the search can be extended to

the LHC. I will then follow this by a discussion of the CP mixing

induced in the Higgs sector due to the above-mentioned CPV in the

soft SUSY breaking parameters and its effects on the Higgs

phenomenology at the LHC. I would then point out some interesting

aspects of the phenomenology of a moderately light charged Higgs

boson, consistent with the LEP constraints, in this scenario. Decay

of such a charged Higgs boson would also allow a probe of a light

($\lesssim$50 GeV), CP-violating (CPV)  Higgs boson. Such a light

neutral Higgs boson might have escaped detection at LEP and could

also be missed at the LHC in the usual search channels.

 

Keywords. Supersymmetry; CP violation; Higgs sector; large hadron

collider.
