From small to large x: toward a unified description of high energy collisions

Abstract

Abstract Inclusive particle production at high pt (equivalently intermediate to large x) in high energy hadronic collisions is successfully described by perturbative QCD, using the collinear-factorization formalism. On the other hand at very high energies and not so high pt the Color Glass Condensate (CGC) formalism has been quite successful in describing particle production at small Bjorken x. Here we propose a way to unify the two approaches which enables one to apply it to particle production at all x (all pt ).
