"DGLAP (Dokshitzer\u2013Gribov\u2013Lipatov\u2013Altarelli\u2013Parisi) are the authors who first wrote the QCD evolution equation of the same name. DGLAP was first published in the western world by Altarelli and Parisi in 1977, hence DGLAP and its specialisations are sometimes still called Altarelli\u2013Parisi equations."@en .
