Abstract

The decay of heavy orthoquarkonium into quark-antiquark pair and two gluons is considered. The differential probability of the decay in the tree approximation is calculated and the probability distributions of quarks and gluons are obtained. The collinear enhancement of the bottomonium decay is shown to take place at the uū-, [Formula: see text] and [Formula: see text]-pairs production but is absent at the [Formula: see text]-pair production. Some other peculiarities of the considered decays are discussed.
