Özet

The non-Abelian gauge structure of the Standard Model implies the presence of the multi-boson self interactions. Precise measurements in experimental and theoretical studies of these interactions allow not only testing the nature of the Standard Model but also new physics contribution coming from the beyond Standard Model. These interactions can be examined using a model-independent way in effective theory approach that composes the motivation part of this study. In this paper, we examine the anomalous ZZ gamma and Z gamma gamma neutral triple gauge couplings via the process e-e+ -> Z gamma for the neutrino-antineutrino pair decay of Z boson. It has performed with both unpolarized and polarized electron beams at the Compact Linear Collider with root s = 3 TeV. The study focused on CP-conserving C-BW/(4) and CP-violating CBB/(4), CBW/(4), CWW/(4) couplings. Obtained sensitivities on the anomalous neutral triple gauge couplings with 95% Confidence Level are given with systematic uncertainties of 0%, 5% and 10% for unpolarized, -80% and 80% polarized electron beams with integrated luminosities of L-int = 5 ab(-1), L -> = 4 ab(-1) and Lint = 1 ab(-1), respectively. Comparing the latest experimental limits and related phenomenological studies, our results on the anomalous neutral gauge couplings are set more stringent sensitivity between 10-30 times of magnitude.
