Fate of k_perp-factorization for hard processes in nuclear environment | | N.N. Nikolaev
; | | Date: |
15 Dec 2004 | | Subject: | hep-ph | | Affiliation: | Institut f. Kernphysik, Forschungszentrum Jülich, Germany and L.D.Landau Institute for Theoretical Physics, Chernogolovka, Russia | | Abstract: | Large thickness of heavy nuclei brings in a new scale into the pQCD description of hard processes in nuclear environment. The familiar linear $k_{perp}$-factorization breaks down and must be replaced by a new concept of the nonlinear $k_{perp}$-factorization introduced in cite{Nonlinear}. I demonstrate the salient features of nonlinear $k_{perp}$-factorization on an example of hard dijet production in DIS off heavy nuclei. I also discuss briefly the non-linear BFKL evolution for gluon density of nuclei. | | Source: | arXiv, hep-ph/0412211 | | Services: | Forum | Review | PDF | Favorites | |
