On leptonic decay of a heavy quarkonium with a Higgs-boson emission
Abstract
Description
A leptonic $(\bar l l)$ decay of a heavy quark-antiquark bound state $T(\bar QQ)$ with a Higgs-boson $H$ emission is investigated. The applying of the well-known low-energy theorem to meson-Higgs coupling allows one to estimate the probability of the decay $T(\bar QQ)\to \bar ll H$. The only a simple version of the Standard Model extension containing two-Higgs doublet is considered.
