Light quark contributions to Higgs decays

High Energy Physics - Phenomenology 2025-02-05 v1

Abstract

The literature establishes that the light fermions contributions to the decays HZγH\to Z\gamma and HγγH\to\gamma\gamma are negligible since their coupling with the Higgs is proportional to mfm_f. In the present letter, we show that although such a conclusion is true for leptons, the light quark contributions are zero when we consider their non-perturbative effects.
