›Longitudinal WW scattering in light of the 'Higgs' discovery
Institute of Cosmos Sciences (ICC), Barcelona University.
WW scattering is dominated at high energies by their longitudinal components, which are the most sensitive to the nature of the electroweak symmetry breaking. Prior to the discovery at the LHC of a Higgs-like particle, unitarization tools were extensively used to show that, in the absence of a light Higgs boson, new resonances resulting from the would-be strongly-interacting electroweak sector would appear, and furthermore these techniques would approximately predict their masses, widths, and signal strengths. With the discovery of a Higgs-like particle now firmly established, and assuming that this particle couples approximately as in the SM, but still being open to the possibility of an extended symmetry breaking sector, we apply the same unitarization methods to demonstrate how new resonances could still appear in the scattering of EW vector bosons and we discuss their ability to be probed with current and future LHC data.
