Description
Parton distribution functions (PDFs) are most commonly determined by parameterizing them at some input scale Q_0 and then evolved to the desired scale Q through the DGLAP evolution equations. Extensions of the DGLAP equations have been proposed to account not only for the splitting of partons but also including non-linear 1/Q^n terms from the recombination of partons which slows down the pace of DGLAP evolution at small x. At sufficiently low Q the non-linear terms will eventually become the dominant ones and one enters the so-called saturation regime. In the work reported here, we have implemented a model for the leading 1/Q corrections in the DGLAP evolution code HOPPET and coupled it with xFitter to perform new global PDF fits accounting for the effects of recombination.
