New Effective Feynman-like Rules for the Multi-Regge QCD Asymptotics of Inclusive Multijet Production
Victor T. Kim, Grigorii B. Pivovarov
Abstract
New effective Feynman-like rules are defined for inclusive multijet cross sections in the multi-Regge regime. The solution of the BFKL equation is used as a starting point. The resulting rules involve conformal weight and rapidity as a momentum and a coordinate respectively and are translation invariant in the coordinates. We use the effective rules to calculate ultra high energy asymptotics of inclusive multijet production. The dependence on the parton densities occurs only in the overall normalization of the asymptotic cross sections.
