Anomalous production of massive gauge boson pairs at muon colliders

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 $\sqrt{s}=6$, 10, and 30 TeV, corresponding to an integrated luminosity of 4, 10, and $10\text{ }\text{ }{\mathrm{ab}}^{\ensuremath{-}1}$, respectively. Simulated $\ensuremath{\mu}\ensuremath{\mu}\ensuremath{\rightarrow}\mathrm{W}\mathrm{W}+\ensuremath{\nu}\ensuremath{\nu}/\ensuremath{\mu}\ensuremath{\mu}$ 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, $\ensuremath{\mu}\ensuremath{\mu}\ensuremath{\rightarrow}\mathrm{W}\mathrm{W}/\mathrm{Z}\mathrm{Z}+\ensuremath{\nu}\ensuremath{\nu}$ 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.
