Direct connection between the different QCD orders for parton
distribution and fragmentation functions [PDF]
O. Yu. ShevchenkoThe formulas directly connecting parton distribution functions (PDFs) and fragmentation functions (FFs) at the next to leading order (NLO) QCD with the same quantities at the leading order (LO) are derived. These formulas are universal, i.e. have the same form for all kinds of PDFs and FFs, differing only in the respective splitting functions entering there.View original: http://arxiv.org/abs/1303.6087
