Quartic Gauge Boson Couplings

Quartic vertices provide a window into one of the most important problems in particle physics; the understanding of electroweak symmetry breaking. I survey the various processes that have been proposed to study quartic gauge boson couplings at future ee, eγ, γγ, e−e−, and pp colliders. For the lowest dimension operators that do not include photons, it appears that the LHC will provide the most constraining measurements. However, precision measurements at high energy ee colliders involving WW rescattering are also quite sensitive to the effects of a strongly interacting weak interaction. For quartic couplings involving photons, γγ collisions appear to be the best place to measure these couplings. Measurements using gauge boson production in eγ collisions are almost as precise as the γγ processes with ee → V V V about an order or magnitude less sensitive.
