Higgs boson decay to paired $B_c$: relativistic and one-loop corrections

Abstract

The exclusive decays of the Higgs boson to $B_c{B}_c$ and $B_c^{\ast }{B}_c^{\ast }$ pairs are studied. The hard parts of the decay amplitudes are estimated within the perturbative Standard Model up to one-loop corrections. The soft fusion of heavy quarks to the quarkonium is described in framework of the relativistic quark model.
