Muon Collider Sensitivity to Anomalous Quartic Gauge Couplings

A muon collider has two main advantages over the Large Hadron Collider regarding sensitivity to anomalous quartic gauge couplings (aQGCs); it effectively serves as a gauge boson collider due to collinear divergences, and it has access to the full center of mass (CoM) energy for collisions due to muons being fundamental particles (as opposed to hadrons). 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.
