Evolution of twist-3 fragmentation functions in multicolour QCD and the Gribov-Lipatov reciprocity

Abstract

It is shown that twist-3 fragmentation functions in the large-$N_c$ limit of QCD obey the DGLAP evolution equations. The anomalous dimensions are found explicitly. The Gribov-Lipatov reciprocity is violated at the twist-3 level in the leading logarithmic approximation.
