The diffractive structure function at the Tevatron: CDF results

Results on hard diffraction from CDF are reviewed with emphasis on the determination of the diffractive structure function of the (anti)proton from single diffractive and double Pomeron exchange dijet production. Comparison of the diffractive dijet results with predictions based on diffractive deep inelastic scattering at HERA shows a breakdown of conventional QCD factorization. A similar breakdown is observed within the CDF results in comparing the structure functions obtained from single diffraction and double Pomeron exchange.Comment: 10 pages, Late

Aspects of Diffraction at the Tevatron

Results on soft and hard diffraction obtained by the CDF Collaboration at the Fermilab Tevatron proton-antiproton Collider are reviewed with emphasis on aspects of the data that point to the underlying QCD mechanism for diffraction. The results are interpreted in terms of a phenomenological approach in which diffraction is due to an exchange of low-x partons subject to color constraints.Comment: 5 pages, Presented at Conference on the Intersections of Particle and Nuclear Physics (CIPANP-2003), New York City, 19-24 May 200
