摘要：

Utilizing very recent deep inelastic scattering measurements, a QCD analysis of proton structure function F-2(p) (x, Q(2)) is presented. A wide range of the inclusive neutral-current deep-inelastic-scattering (NC DIS) data used in order to extract an updated set of parton distribution functions (PDFs). The HERA 'combined' data set on sigma(+/-)(r,NC)(x, Q(2)) together with all available published data for heavy quarks F-2(c,b) (x,Q(2)), longitudinal F-L (x, Q(2)) and also very recent reduced DIS cross section sigma(+/-)(r,NC)(x, Q(2)) data from HERA experiments are the input in the present next-to-leading order (NLO) QCD analysis which determines a new set of parton distributions, called KKT11C.. The extracted PDFs in the 'fixed flavour number scheme' (FFNS) are in very good agreement with the available theoretical models.
