Triple Vector Boson Production at the LHC

The interaction among vector bosons is crucial to understanding electroweak symmetry breaking. At the LHC one technique is to use "tag" jets to identify vector boson fusion processes leading to two vector bosons and two "tag" jets in the final state. Another approach is to study the production of three vector bosons in the final state. There is a clear tradeoff since in the latter case clear "tags" are not available, although the cross sections are substantially larger than those for vector boson fusion.
