Non-perturbaitve effects in Higgs boson decays to electroweak vector bosons and photons

Alexander Khodjamirian, Kirill Melnikov, Arkady Vainshtein

We estimate the magnitude of the leading non-perturbative QCD corrections to the decays of the Higgs boson to the ${\hat{I}}^{3}Z$ and ${\hat{I}}^3{\hat{I}}^3$ final states. These corrections originate from th…
