Smallx nuclear shadowing from diffractive scattering
Abstract
We calculate nuclear shadowing ratios at small Bjorkenx for nuclei in the mass range 3<A<239 in the framework of a generalized form of the Gribov theory. The diffractive dissociation cross sections needed as inputs are taken from the FNAL (Fermi National Laboratory) and HERA (HadronElectron Ring Accelerator) experiments. Our calculations cover a wide range of energies between 12.8 and 231 GeV. The effects of the inclusion of subleading Reggeons on nuclear shadowing are investigated. At lower energies our results are compared to available data from the New Muon Collaboration (NMC) and E665 Collaboration (E665) experiments at x{approx_equal}10{sup 4}. At higher energies subleading Reggeons are found to contribute significantly to nuclear shadowing.

We calculate the nuclear shadowing ratio for a wide range of nuclei at small Bjorkenx in the framework of Gribov theory. The coherent contribution to the (virtual) photonnucleon cross section is obtained in terms of the diffractive dissociation cross section. Information on diffraction from FNAL and HERA is used. Our results are compared to available data from the New Muon Collaboration and E665 Collaboration experiments at x{approx_equal}10{sup 4}.

Leading twist nuclear shadowing, nuclear generalized parton distributions, and nuclear deeply virtual Compton scattering at small x
We generalize the leading twist theory of nuclear shadowing and calculate quark and gluon generalized parton distributions (GPDs) of spinless nuclei. We predict very large nuclear shadowing for nuclear GPDs. In the limit of the purely transverse momentum transfer, our nuclear GPDs become impactparameterdependent nuclear parton distribution functions (PDFs). Nuclear shadowing induces nontrivial correlations between the impact parameter b and the lightcone fraction x. We make predictions for the deeply virtual Compton scattering (DVCS) amplitude and the DVCS cross section on {sup 208}Pb at high energies. We calculate the cross section of the BetheHeitler (BH) process and address the issuemore »

Effect of shadowing on electromagnetic scattering from rough ocean wavelike surfaces at small grazing angles
A hybrid momentmethod/geometricaltheoryofdiffraction technique (MM/GTD) has been implemented to numerically calculate the electromagnetic scattering from onedimensionally rough surfaces at extreme illumination angles (down to 0{degree} grazing). The hybrid approach allows the extension of the modeled scattering surface to infinity, avoiding the artificial edge diffraction that prevents use of the standard moment method at the smallest grazing angles. Numerical calculation of the backscattering from slightly rough largescale surfaces approximating ocean wave features shows that roughness in strongly shadowed regions can contribute significantly to the total backscatter at vertical polarization. This is observed when the shadowing obstacle is several wavelengths high, andmore » 
Probing the Small $x$ Gluon Tomography in Correlated Hard Diffractive Dijet Production in Deep Inelastic Scattering
The close connection between the quantum phase space Wigner distribution of smallx gluons and the color dipole scattering amplitude is investigated, and studying it experimentally is proposed in the hard diffractive dijet production at the planned electronion collider. The angular correlation between the nucleon recoiled momentum and the dijet transverse momentum probes the nontrivial correlation in the phase space Wigner distribution. This experimental study not only provides threedimensional tomographic pictures of gluons inside high energy protons  it gives a unique and interesting signal for the smallx dynamics with QCD evolution effects.
