High Q2 Neutral and Charged Current Cross Sections and Structure Functions Measured by H1

Measurements of the neutral and charged current cross sections at high values of four momentum transfer Q², performed by the H1 experiment at HERA are presented. The NC cross sections are used to determine the structure functions F₂, xF₃ and F_L. The W propagator mass is derived using CC cross sections. Valence quark densities are extracted from all measured cross sections. The new measurements are found to be fully consistent with the Standard Model.
