Model-independent analysis of Higgs spin and CP properties in the process $e^+ e^- \to t \bar t \Phi$ / Godbole, R.M. (CERN ; Utrecht U.) ; Hangst, C. (KIT, Karlsruhe) ; Muhlleitner, M. (KIT, Karlsruhe) ; Rindani, S.D. (Ahmedabad, Phys. Res. Lab) ; Sharma, P. (Ahmedabad, Phys. Res. Lab)
In this paper we investigate methods to study the $t\bar{t}$ Higgs coupling. The spin and CP properties of a Higgs boson are analysed in a model-independent way in its associated production with a $t\bar{t}$ pair in high-energy $e^+e^-$ collisions. [...]

Top polarization, forward-backward asymmetry and new physics / Choudhury, Debajyoti (Delhi U.) ; Godbole, Rohini M. (CERN) ; Rindani, Saurabh D. (Ahmedabad, Phys. Res. Lab) ; Saha, Pratishruti (Delhi U.)
We consider how the measurement of top polarization at the Tevatron can be used to characterise and discriminate among different new physics models that have been suggested to explain the anomalous top forward-backward asymmetry reported at the Tevatron. This has the advantage of catching the essence of the parity violating effect characteristic to the different suggested new physics models. [...]

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. [...]

Strong gauge boson scattering at the LHC / Rindani, S.D. (Ahmedabad, Phys. Res. Lab)
In the standard model with electroweak symmetry breaking through the Higgs mechanism, electroweak gauge-boson scattering amplitudes are large if the Higgs boson is heavy, and electroweak gauge interactions become strong. In theories with electroweak symmetry breaking through alternative mechanisms, there could be a strongly interacting gauge sector, possibly with resonances in an accessible energy region. [...]

One of the main endeavors at future high-energy colliders is the search for the Higgs boson(s) and, once found, the probe of the fundamental properties. In particular, the charge conjugation and parity (CP) quantum numbers have to be determined. [...]

Determining the CP properties of the Higgs boson / Bhupal Dev, P.S. (Bangalore, Indian Inst. Sci.) ; Djouadi, A. (Orsay, LPT) ; Godbole, R.M. (Bangalore, Indian Inst. Sci.) ; Muhlleitner, M.M. (CERN ; Annecy, LAPTH) ; Rindani, S.D. (Ahmedabad, Phys. Res. Lab)
The search and the probe of the fundamental properties of Higgs boson(s) and, in particular, the determination of their charge conjugation and parity (CP) quantum numbers, is one of the main tasks of future high-energy colliders. We demonstrate that the CP properties of a Standard Model-like Higgs particle can be unambiguously assessed by measuring just the total cross section and the top polarization in associated Higgs production with top quark pairs in e+e- collisions..

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. [...]
