An EFT hunter’s guide to two-to-two scattering: HEFT and SMEFT on-shell amplitudes
Abstract We derive the contact terms contributing to the four-point amplitudes of the standard model particles, keeping terms with up to quartic energy growth. Imposing just the unbroken low-energy symmetry, and treating the electroweak gauge bosons and the Higgs as independent degrees of freedom, w...
