A study on DIM-8 neutral triple gauge couplings via ZZ production at future hadron colliders

Up to date, the Standard Model is in agreement with most of the available experimental data. However, SM does not allow for neutrino masses observed experimentally. Other failures of the SM include the absence of gravity in its formalism and the absence of Dark Matter candidates. All these issues indicate that there is a need for a new physics beyond SM. The non-abelian feature of the 〖SU (2)〗_L gauge symmetry, one of the gauge symmetry groups in the SM, prevents self-interactions such as ZZZ and and ZZγ at tree-level. The coupling constants of these interactions are referred as neutral triple gauge couplings (NTGC). These couplings are present in many extensions beyond SM physics. Consequently, the signature of new physics beyond SM can be searched through the possible deviation from the predicted SM values of NTGC. In this thesis, we investigate the sensitivity of anomalous triple gauge couplings via ppZZ process for various future circular hadron colliders options (HL-LHC, HE-LHC, LE-FCC, and FCC) with Effective Field Theory Approach. For these colliders, we find that the limits on all effective couplings derived from the processes under consideration are loose in the case of HL-LHC collider. Besides, we show that the FCC-hh collider gives the best 95% C.L limits on all effective couplings compared to the other colliders. Moreover, our derived limits on all effective couplings are stringint compared to the ones reported by ATLAS and CMS collaborations as will be displayed in the thesis.
