ZEUS NLO QCD fits

Abstract

NLO QCD fits using the DGLAP formalism have been made to the high precision ZEUS $e^{+}p$ reduced cross-section data and to fixed target structure function data, in order to detrmine parton distribution functions and the value of ${\alpha }_s(M_Z^2)$, taking full account of correlated systematic errors. Preliminary results are reported.
