abstract
The Higgs discovery has given us the Higgs-gauge sector as a new handle to search for physics beyond the Standard Model. This includes physics scenarios originally linked to massive gauge boson scattering at high energies. We investigate how one can separately probe the Higgs couplings to the longitudinal and transverse parts of the massive gauge bosons away from this high-energy limit. Deviations from the Standard Model could originate from higher-dimensional operators, compositeness, or even more fundamentally from a violation of gauge invariance. The signature we propose is the tagging jet kinematics in weak boson scattering for scattering energies close to the Higgs resonance. During the upcoming LHC run at 13 TeV we will be able to test these couplings at the 20% level.
