Description
We show the new relationship between the anomalous dimensions, resummed
through next-to-next-to-leading-logarithmic order, in the
Dokshitzer-Gribov-Lipatov-Altarelli-Parisi (DGLAP) evolution equations for
the first Mellin moments of the quark and gluon fragmentation functions,
which correspond to the average hadron multiplicities in jets initiated by
quarks and gluons, respectively. This relationship strongly improves
previous treatments by allowing for an exact solution of the evolution
equations. So far, such relationships have only been known from
supersymmetric QCD.
