Abstract

We present a field redefinition that simplifies the Higgs Effective Field Theory Lagrangian for the Electroweak Symmetry Breaking Sector. This simplification produces the same on-shell scattering amplitudes while greatly reducing the number of contributing Feynman diagrams for ωω→ n× h processes (which approximate the W_LW_L→ n× h amplitudes at the TeV scale by means of the Equivalence Theorem).
