Muon Collider Sensitivity to Anomalous Quartic Gauge Couplings

A muon collider has one primary advantage over the Large Hadron Collider (LHC) regarding sensitivity to anomalous quartic gauge couplings (aQGCs); it effectively serves as a gauge boson collider due to collinear divergences which serves to increase the rate of these rare interactions. We study the sensitivity of a muon collider to dimension-8 operators affecting the WWZγ, WWZZ, and WWγγ vertices. The μ+ μ- W+ W- final state in the vector boson scattering topology is analyzed and expected limits on the energy of new physics are set for 6, 10, and 30 TeV center of mass colliding energies. Expected limits set at all center of mass points are stronger than corresponding limits observed at the LHC by the CMS collaboration at 13 TeV.
