Uncertainties on diffractive parton distribution functions from fit to the HERA data.

S. Taheri Monfared, Ali N. Khorramian & S. Atashbar Tehrani
In the present QCD analysis, we use a wide range of the inclusive diffractive deep inelastic scattering observable based on different methods of data selections. Diffractive parton distribution and their uncertainty bands are determined from a global fit in the next-to-leading order (NLO). Predictions based on the extracted diffractive parton densities are compared to the available theoretical models. Satisfactory agreement exists.
