Paired Double Heavy Baryons Production in Decays of the Higgs Boson

Rare decays of the Higgs boson into a pair of diquarks cc(bb) and c over bar c over bar (b over bar b over bar ) are studied within the perturbative Standard Model and relativistic quark model. The relativistic corrections determined by the relative motion of quarks are calculated using the production amplitude and the diquark wave functions. Numerical values of the decay widths of the Higgs boson into a baryon pair ccq(bbq) and c over bar c over bar q over bar (b over bar b over bar q over bar ) are obtained.
