Research Exposures

I studied spin-polarization of spin-1 particle and constructed the complete set of 8 polarization observables and measured them for ZW in the case of ZV , W+W, W±V production at ILC and LHC in analytic approach as wel as in numerical aproach in Event generator MadGraph5. I used the polarization observables of Z boson to study anomalous triple gauge boson couplings in the processes ZV , W+W, W±V production at ILC (with and without polarized beams) as well as at LHC and obtained constraints on the anomalous couplings. We are studying FCNC interaction in single top production at LHeC using the Z boson spin observables.
