Probing CP-violating Higgs contributions in $\gamma-\gamma -> f anti-f$ through fermion polarization / Godbole, Rohini M (CERN) ; Kraml, Sabine (CERN) ; Rindani, S D (Physical Research Laboratory, Navrangapura, Ahmedabad, India) ; Singh, R K (Laboratoire de Physique The´orique, Orsay, France)
We discuss the use of fermion polarization for studying neutral Higgs bosons at a photon collider. To this aim we construct polarization asymmetries which can isolate the contribution of a Higgs boson $\phi$ in $\gamma\gamma\to f \bar f$, $f=\tau/t$, from that of the QED continuum. [...]

Study of CP Property of the Higgs at a Photon Collider using $\gamma\gamma\to t\bar t\to l X $ / Godbole, Rohini M. (CERN) ; Rindani, Saurabh D. (ICTP, Trieste) ; Singh, Ritesh K. (Bangalore, Indian Inst. Sci.)
We study possible effects of CP violation in the Higgs sector on $t\bar t$ production at a $\gamma\gamma$-collider. These studies are performed in a model-independent way in terms of six form-factors $\{\Re(S_{\gamma}), \Im(S_{\gamma}), \Re(P_{\gamma}), \Im(P_{\gamma}), S_t, P_t\}$ which parametrize the CP mixing in the Higgs sector, and a strategy for their determination is developed.

Fermion polarization in sfermion decays as a probe of CP phases in the MSSM / Gajdosik, Thomas (Vilnius, Inst. Phys.) ; Godbole, Rohini M. (Bangalore, Indian Inst. Sci.) ; Kraml, Sabine (Vienna, OAW ; CERN)
The longitudinal polarization of fermions (tops and taus) produced in sfermion decays to neutralinos or charginos can be a useful tool for the determination of SUSY parameters. We discuss this fermion polarization in the context of the MSSM with complex parameters. [...]

On measurement of top polarization as a probe of $t \bar t$ production mechanisms at the LHC / Godbole, Rohini M (CERN) ; Rao, Kumar (Helsinki U. ; Helsinki Inst. of Phys.) ; Rindani, Saurabh D (Ahmedabad, Phys. Res. Lab) ; Singh, Ritesh K (Wurzburg U.)
In this note we demonstrate the use of top polarization in the study of $t \bar t$ resonances at the LHC, in the possible case where the dynamics implies a non-zero top polarization. As a probe of top polarization we construct an asymmetry in the decay-lepton azimuthal angle distribution (corresponding to the sign of $\cos\phi_\ell$) in the laboratory. [...]

Probing the CP of the Higgs at a $\gamma \gamma$ collider using $\gamma \gamma \to t \bar t \to lX$ / Godbole, R.M. (CERN) ; Rindani, S.D. (Ahmedabad, Phys. Res. Lab) ; Singh, R.K. (Bangalore, Indian Inst. Sci.)
We present results of an investigation to study CP violation in the Higgs sector in $t\bar t$ production at a $\gamma\gamma$-collider. This is done in a model independent way in terms of six form-factors $\{\Re(S_{\gamma}), \Im(S_{\gamma}), \Re(P_{\gamma}), \Im(P_{\gamma}), S_t, P_t\}$ which parameterize the CP mixing in Higgs sector.
