    We review the extension of the factorization formalism of perturbative QCD to soft rescattering associated with hard processes in nuclei.Comment: Latex 16 pages, including 18 figures, to appear in the Proceedings of Hard Probe Collaboratio

    J/ψ\psi production and suppression in nuclear collisions

    Full text link
    In terms of a new QCD factorization formula for J/ψ\psi production, we calculate the J/ψ\psi suppression in nuclear collisions by including the multiple scattering between the pre-J/ψ\psi partonic states and the nuclear medium. We find agreement with all data on J/ψ\psi suppression in hadron-nucleus and nucleus-nucleus collisions, except a couple of points (the ``second drop'') at the highest ETE_T bins of the new NA50 data.Comment: Latex, 4 pages, to appear in the proceedings of Quark Matter 200

    We report a summary of the structure function working group which covers a wide range of the recent results from HERA, Tevatron, RHIC, and JLab experiments, and many theoretical issues from low x to high x.Comment: 20 pages, presented at 13th International Workshop on Deep Inelastic Scattering (DIS 05), Madison, Wisconsin, 27 Apr - 1 May 200
