Abstract

H1 has measured the diffractive DIS cross section ep → eXY using data from both of the HERA data-taking periods. Using new measurements of the diffractive cross section at different centre-of-mass energies, the diffractive longitudinal structure function F_L^D has been extracted. The results are in agreement with NLO QCD predictions based on fits to inclusive data. New high statistics measurements of the diffractive reduced cross section σ_r^D have been made using two experimental methods covering the accessible kinematic range. This precise dataset agrees well with QCD-based predictions.
