Abstract
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 \({\sigma_{r,NC}^\pm (x,Q^2)}\) 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 \({\sigma_{r,NC}^\pm (x,Q^2)}\) 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 \({{\tt KKT11C}}\). The extracted PDFs in the ‘fixed flavour number scheme’ (FFNS) are in very good agreement with the available theoretical models.
