Heavy fermion corrections to heavy Higgs-Boson production and decay

Research output: Contribution to journal › Article › peer-review

Abstract

We calculate the O(g²m_f²/M_w²) fermionic corrections to the Higgs-boson coupling to W and Z bosons in the limit m_f ≫ M_w. We find that these corrections decrease the partial width of Higgs-boson decays to W- and Z-boson pairs by up to 75% for fermion and Higgs-boson masses allowed by perturbative unitarity. The same suppression applies to Higgs-boson production via W- and Z-boson fusion.
