Abstract
The parton momentum density distributions of the proton are determined
from a next-to-leading order QCD analysis of structure functions
measured at HERA and by fixed target experiments. Also included
are data
on the difference of the up and down anti-quark distributions.
The
uncertainties in the parton densities, structure functions and
related
cross sections are estimated from the experimental errors and
those on
the input parameters of the fit. Several QCD predictions based
on the
parton densities obtained from this analysis are calculated and
compared
to data.
