The one loop renormalization of the effective Higgs sector and its implications

الأصل · EN

We study the one-loop renormalization the standard model with anomalous Higgs couplings (O(p²)) by using the background field method, and provide the whole divergence structure at one loop level. The one-loop divergence structure indicates that, under the quantum corrections, only after taking into account the mass terms of Z bosons (O(p²)) and the whole bosonic sector of the electroweak chiral Lagrangian (O(p⁴)), can the effective Lagrangian be complete up to O(p⁴).
