Abstract
The fragmentation function of a scalar leptoquark into possible -wave bound states with a heavy antiquark is calculated to the leading order in perturbative QCD for the high energy processes at large transverse momenta. The one-loop equations for the evolution of moments of the fragmentation function due to the hard gluon emission by the leptoquark are derived. The integral probabilities of fragmentation are evaluated.
