The data were taken at a centre-of-mass energy of √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, Q2, between 60 and 50000 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 xF3γ Z. A measurement of the neutral current parity violating structure function F2γ 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. -

The data were taken with the H1 detector in the years 2006 and 2007 and correspond to an integrated luminosity of 122 pb-1. The semi-inclusive cross section is measured in the phase space defined by the photon virtuality 6
