DGLAP evolution equations
Template:Primary The Dokshitzer–Gribov–Lipatov–Altarelli–Parisi (DGLAP) evolution equations are equations in QCD describing the variation of parton distribution functions with varying energy scales.[1] Experimentally observed scaling violation in deep inelastic scattering is important evidence for the correctness of the equations and of QCD in general.[1] The equations were first published in the western world by Guido Altarelli and Giorgio Parisi in 1977, and so are still sometimes called the Altarelli–Parisi equations.[2] Only later did it become known that an equivalent formula had been published in Russia by Template:Ill in 1977,[3] and by Vladimir Gribov and Lev Lipatov in 1972.[4]
The DGLAP QCD evolution equations are widely used in global determinations of parton distributions, like those from the CTEQ or NNPDF collaborations.Script error: No such module "Unsubst".
