Description
ew precision measurements of the double-differential inclusive
neutral-current cross section, measured with the ZEUS detector at
HERA at a centre-of-mass energy of 318 GeV in e+p and e-p collisions
are shown. They span the kinematic domain of high momentum
transfer Q^2>650 GeV^2 and high Bjorken-x~1.
Using the HERA data collected at three different centre-of-mass
energies, both the collaborations H1 and ZEUS have updated their
measurements of the longitudinal structure function F_L. The structure
function is measured in the kinematic region of momentum transfer
1.5<Q^2<800 GeV^2 and Bjorken-x 3x10^-4 <x<0.03. The measurements are
compared to predictions from the Standard model, based on a variety of parton
density functions.
