On leptonic decay of a heavy quarkonium with a Higgs-boson emission
G. A. Kozlov
Abstract
A leptonic ( l l) decay of a heavy quark-antiquark bound state T( 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( QQ) ll H. The only a simple version of the Standard Model extension containing two-Higgs doublet is considered.
