Double vector quarkonia production in exclusive Higgs boson decays

Abstract

Partial decay widths and branching fractions are calculated for the exclusive decays of the Standard Model Higgs boson into a pair of vector quarkonium states, $H\to J/\psi J/\psi ,H\to {\rm Y}{\rm Y},H\to J/\psi \varphi ,H\to J/\psi {\rm Y}$, with relativistic corrections due to quark motion in mesons taken into account.
