Diffractive parton distributions from the analysis with higher twist
arXiv:0704.1608 · doi:10.1103/PhysRevD.76.114014
Abstract
Diffractive parton distributions of the proton are determined from fits to diffractive data from HERA. In addition to the twist--2 contribution, the twist--4 contribution from longitudinally polarised virtual photons is considered, which is important in the region of small diffractive masses. A new prediction for the longitudinal diffractive structure function is presented which differs significantly from that obtained in the pure twist--2 analyses.
