Higgs boson decay to the pair of S- and P-wave Bc mesons
Abstract
We investigate the rare production of the pair of S- and P- wave Bc-meson in the Higgs boson decay in the perturbative Standard Model and relativistic quark model. Relativistic amplitudes and decay widths are constructed with the account of the relative motion of heavy quarks forming Bc mesons. When constructing the Higgs boson decay amplitudes, the method of projection operators on the S- and P-wave states of quarks is used. Relativistic corrections are expressed in terms of special relativistic parameters and are calculated numerically in the quark model. The dependence of the decay widths of the Higgs boson on various sources of relativistic corrections is investigated.
