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.
