Description
New measurements of the differential cross sections for neutral
current deep inelastic ep collisions up to Bjorken-x values equal to
one are presented. The measurements were performed using the data
collected with the ZEUS detector at HERA with sqrt(s) = 318 GeV and an
integrated luminosities of 142(187) pb-1 for e+p(e-p) collisions.
A new method was employed to reconstruct the kinematic variables
and measure the cross sections for Q2 > 575 GeV^2. The data are
considerably more precise than previously published measurements
in this kinematic region and provide interesting tests of the
parameterizations of the behavior of the cross section up to x=1.
