Özet
In this study, we investigate the potential of mu(-)mu(+) -> Z gamma -> v v gamma process at the future muon collider with a center-of mass energy of 3 TeV to examine the anomalous ZZ gamma and Z gamma gamma neutral triple gauge couplings defining CP-conserving CB?W/A(4) coupling and three CP-violating CBB/A(4), CBW/A(4), CWW/A(4) couplings. All signal and relevant background events are generated in MadGraph and passed through Pythia for parton showering and hadronization. Detector effects are also considered via tuned muon detector cards in Delphes. The effects of systematic uncertainties of 0%, 3% and 5% on the sensitivities are studied. The best sensitivities obtained from the process mu(-)mu(+) -> Z gamma -> v v gamma are [-6.53; 6.64]x 10(-2) TeV-4 on CP-conserving CB?W/A(4) coupling and [-2.47; 2.47] x 10(-2) TeV-4, [-8.46; 8.46] x 10(-2) TeV(-4 )and [-2.20; 2.20] x 10(-1 )TeV(-4) on CP-conserving CBB/A4, CBW/A4, CWW/A4 couplings , respectively. Our obtained results on the anomalous neutral gauge couplings set more stringent sensitivity, ranging between 5 and 15 times than the current experimental results while slightly better than the phenomenological studies at future pp colliders such as the HL-LHC, the HE-LHC and the FCC-hh, respectively. On the other hand, we can see that the bounds on the anomalous neutral gauge couplings expected to be obtained for the future e-e+ colliders such as the CLIC are roughly 2 times better than our results.
