Measurement of high-Q 2 charged current cross sections in e + p deep inelastic scattering at HERA
Cross sections for e

p charged current deep inelastic scattering at a centre-of-mass energy of have been determined with an integrated luminosity of
collected with the ZEUS detector at HERA. The differential cross sections

and . The predictions of the Standard Model agree well with the measured cross sections. The mass of the W boson propagator is determined to be
from a fit to
. The chiral structure of the Standard Model is also investigated in terms of the (1-y)2 dependence of the double-differential cross section. The structure-function
has been extracted by combining the measurements presented here with previous ZEUS results from e
-
p scattering, extending the measurement obtained in a neutrino-nucleus scattering experiment to a significantly higher Q
2 region.
