| Perturbative Fragmentation of a Scalar Leptoquark into a Heavy Lepto-Quarkonium | ||
| Protvino, 1997.- p.10, figs. 5, tables 1, refs.:16. | ||
The fragmentation function of a scalar leptoquark into possible S-wave bound states with a heavy antiquark is calculated in the leading order of the perturbative QCD for the high energy processes at large transverse momenta. The one-loop equations for the $q^2$-evolution of moments of the fragmentation function due to the hard gluon emission by the leptoquark are derived. Integral probabilities of fragmentation are evaluated. The distribution of lepto-quarkonium over the transverse momentum with respect to the fragmentation axis is calculated in the scaling limit.
