Abstract: The very precise combined HERA data provides a testing ground in which
the relevance of novel QCD regimes, other than the successful linear
DGLAP evolution, in small-x inclusive DIS data can be ascertained. We
present a study of the dependence of the AAMQS fits, based on the
running coupling BK non-linear evolution equations (rcBK), on the fitted
dataset. This allows for the identification of the kinematical region
where rcBK accurately describes the data, and thus for the determination
of its applicability boundary. We compare the rcBK results with NNLO
DGLAP fits, obtained with the NNPDF methodology with analogous
kinematical cuts. Further, we explore the impact on LHC phenomenology of
applying stringent kinematical cuts to the low-x HERA data in a DGLAP
fit.
