Inclusive deep inelastic scattering at high Q2 with longitudinally polarised lepton beams at HERA
ABSTRACT Inclusive e ± p single and double differential cross sections for neutral and charged current deep inelastic scattering processes are measured with the H1 detector at HERA. The data were taken at a centre-of-mass energy of s√=319s=319 \sqrt {s} = {319} GeV with a total integrated luminosity...

| Zusammenfassung: | ABSTRACT Inclusive e ± p single and double differential cross sections for neutral and charged current deep inelastic scattering processes are measured with the H1 detector at HERA. The data were taken at a centre-of-mass energy of s√=319s=319 \sqrt {s} = {319} GeV with a total integrated luminosity of 333.7 pb−1 shared between two lepton beam charges and two longitudinal lepton polarisation modes. The differential cross sections are measured in the range of negative four-momentum transfer squared, Q 2, between 60 and 50 000 GeV2, and Bjorken x between 0.0008 and 0.65. The measurements are combined with earlier published unpolarised H1 data to improve statistical precision and used to determine the structure function xFγZ3xF3γZ xF_{3}^{{\gamma Z}} . Ameasurementoftheneutralcurrentparityviolating structure function FγZ2F2γZ F_{2}^{{\gamma Z}} is presented for the first time. The polarisation dependence of the charged current total cross section is also measured. The new measurements are well described by a next-to-leading order QCD fit based on all published H1 inclusive cross section data which are used to extract the parton distribution functions of the proton. |
