Measurement of charged current deep inelastic scattering cross sections with a longitudinally polarised electron beam at HERA
European Physical Journal C 61:2 (2009) 223-235
Abstract:
Measurements of the cross sections for charged current deep inelastic scattering in e - p collisions with longitudinally polarised electron beams are presented. The measurements are based on a data sample with an integrated luminosity of 175 pb-1 collected with the ZEUS detector at HERA at a centre-of-mass energy of 318 GeV. The total cross section is given for positively and negatively polarised electron beams. The differential cross-sections d σ/dQ 2, d σ/dx and d σ/dy are presented for Q 2>200 GeV2. The double-differential cross-section d 2 σ/dxdQ 2 is presented in the kinematic range 280Measurement of charm and beauty production in deep inelastic ep scattering from decays into muons at HERA
