C. Adloff et al., Measurement of neutral and charged current cross-sections in positron-proton collisions at large momentum transfer, EUR PHY J C, 13(4), 2000, pp. 609-639
The inclusive single and double differential cross-sections for neutral and
charged charged processes with four-momentum transfer squared Q(2) between
150 and 30 000 GeV2 and with Bjorken x between 0.0032 and 0.65 are measure
d in e(+)p collisions. The data were taken with the H1 detector at HERA bet
ween 1994 and 1997. and they correspond to an integrated luminosity of 35.6
pb(-1). Tho Q(2) evolution of the parton densities of the proton is tested
, yielding no significant deviation from the prediction of perturbative QCD
. The proton structure function Fz(x, Q(2)) is determined. All extraction o
f the u and d quark distributions at high x is presented. At high Q(2) elec
troweak effects of the heavy bosons Z(o) and W are observed and found to be
consistent with Standard Model expectation.
