Description

We have studied the phenomenological implications of multiple Higgs boson production from longitudinal vector boson scattering in the context of effective field theories. We found compact representations for effective tree-level amplitudes with up to four final state Higgs bosons. Total cross sections are then computed for scenarios relevant at the LHC in which we found the general Higgs Effective Theory (HEFT) prediction avoids the heavy suppression observed in Standard Model Effective Field Theory (SMEFT).
