Contribution

It introduces a relativistic framework for calculating decay amplitudes and widths for heavy quark bound states in Higgs decays, including relativistic corrections.

Findings

Calculated decay widths for charmonium and tetraquark production.

Demonstrated the importance of relativistic corrections in decay amplitude calculations.

Provided theoretical predictions for rare Higgs decay channels.

Abstract

The processes of pair production of S- and P- wave charmonium, as well as the production of the tetraquark (cc \bar{c} \bar{c}) in the Higgs boson decays are investigated within the framework of relativistic quark model. Relativistic decay amplitudes are constructed and decay widths are calculated taking into account relativistic corrections both in the decay amplitude and in the wave function of bound heavy quarks.
