Description

Structure functions and parton densities determined in ep collisions at HERA are reviewed. At HERA, about 0.5 fb^-1 of data were recorded at a centre-of-mass energy of about 320 GeV by each of the two collider experiments H1 and ZEUS. The data samples are about equally shared between operation with e⁺p and e^-p beams. In e⁺p collisions further small samples were collected at reduced centre-of-mass energies. These datasets were used to determine the structure functions F₂, xF₃ and F_L in neutral-current reactions. Together with data from charged current reactions, parton densities of the proton have been determined in a NLO QCD fit. In this talk, the experimental methods applied at HERA and the results are reviewed.
