Anomalous production of massive gauge boson pairs at muon colliders

Abstract

The prospects of searches for anomalous production of hadronically decaying weak boson pairs at proposed high-energy muon colliders are reported. Muon-muon collision events are simulated at s=6, 10, and 30 TeV, corresponding to an integrated luminosity of 4, 10, and 10 ab-1, respectively. Simulated μμ→WW+νν/μμ events are used to set expected constraints on the structure of quartic vector boson interactions in the framework of a dimension-8 effective field theory. Similarly, μμ→WW/ZZ+νν events are used to report constraints on the product of the cross section and branching fraction for vector boson fusion production of a heavy neutral Higgs boson decaying to weak boson pairs. These results are interpreted in the context of the Georgi-Machacek model.
