Anormal Higgs-ayar bozonu bağlaşımların Hvv üretim yoluyla CLIC'te incelenmesi

The effects of CP violating dimension-six operators are investigated through $e^+e^- \to H\nu\bar{\nu}$ process in Standard Model Effective Field Theory approach at each energy stages of CLIC with integrated luminosities. Generation of signal and background events are carried out with using Madgraph and passed this generated events through PYTHIA for hadronization and parton showering at parton level. Realistic detector effects are taken into account with using tuned CLIC detector card that is defined in DELPHES. Since in this thesis the Higgs boson are reconstructed from b-jets pair, the limits on CP-violating dimension-six couplings are obtained at three b-tagging working points: tight, medium and loose defined in the CLICdet Card for three energy stages of CLIC (380 GeV, 1.5, 3 TeV). At 3 TeV center of mass energy of CLIC with integrated luminosity of 5 $ab^{-1}$, on $c_{HW}$ and $c_{HB}$ couplings we had best $95 \%$ C.L. limit values which were $|7.0\times10^{-3}|$ and $|3.0\times10^{-2}|$ for $90 \%$ b-tagging efficiency.
