Saturation and Diffractive DIS
Around 10% of deep inelastic scattering (DIS) events observed at HERA at small value of the Bjorken variable x are diffractive events [1, 2], when the incoming proton stays intact losing only a small fraction xIP of its initial momentum. A large rapidity gap is formed between the scattered proton (or its low mass excitation) and the diffractive system. The ratio of diffractive to total DIS cros...
متن کاملWHERE ARE THE BFKL POMERON and SHADOWING CORRECTIONS IN DIS ?
In this talk, I will argue that the HERA experimental data show that the typical parameter (κ) responsible for the value of the shadowing corrections (SC) in DIS is so large that the BFKL Pomeron is hidden under SC. The SC turn out to be large enough but mostly for the gluon structure function which is not well determined by the available experimental data and by the current theoretical procedu...
متن کاملHigh Density Qcd, Saturation and Diffractive Dis
We review a consistent description of the fusion and saturation of partons in the Lorentz-contracted ultrarelativistic nuclei in terms of a nuclear attenuation of color dipole states of the photon and collective Weizsäcker-Williams (WW) gluon structure function of a nucleus. Diffractive DIS provides a basis for the definition of the WW nuclear glue. The point that all observables for DIS off nu...
متن کاملDiffractive Dis from the Color Dipole Bfkl Pomeron
The microscopic QCD mechanism of diffractive DIS (DDIS) is a grazing, quasielastic scattering of multiparton Fock states of the photon on the target proton, which is best described viewing these Fock states as systems of color dipoles spanned between quarks, antiquarks and gluons [1, 2, 3]. In inclusive DIS, the effect of gluons in the photon is reabsorbed into the Bjorken x dependence of the c...
متن کاملSaturation Effects in Dis at Low X *
We review basic ideas related to saturation of parton densities at small value of the Bjorken variable x. A special emphasis is put on interpreting the results from the ep deep inelastic scattering experiments at HERA.
