On the leptonic decay of a heavy quarkonium with a Higgs-boson emission

Abstract:	The leptonic ( $\mathop l\limits^ - l$ ) decay of a heavy quark-antiquark bound state T( $\bar Q$ Q) with a Higgs-boson H emission is investigated. Applying the low-energy theorem to meson-Higgs coupling allows one to estimate the probability of the decay T( $\bar Q$ Q) → $\mathop l\limits^ - l$ H. Only the simple version of the Standard Model extension containing two-Higgs doublet is considered. The text was submitted by the author in English.
