Searches for multi-Z boson productions and anomalous gauge boson couplings at a muon collider

【摘要】 Multi-boson productions can be exploited as novel probes either for standard model precision tests or new physics searches, and have become a popular research topic in ongoing LHC experiments and future collider studies, including those for electron–positron and muon–muon colliders. In this study, we focus on two examples,i.e., ZZZ direct productions through μ⁺μ^- annihilation at a 1 TeV muon collider, and ZZ productions through vector boson scattering（VBS） at a 10 TeV muon collider, with an integrated luminosity of 10 ab^-1. Various channels are considered, including ZZZ → 4?2ν and ZZZ → 4?+2jets. The expected significance on these multi-Z boson production processes is reported based on a detailed Monte Carlo study and signal background analysis. Sensitivities on anomalous gauge boson couplings are also presented.更多还原
