Running Coupling Effects in BFKL Evolution

高能物理 - 唯象学 2009-10-31 v2

摘要

We resum the recently calculated second order kernel of the BFKL equation. That kernel can be viewed as the sum of a conformally invariant part and a running coupling part. The conformally invariant part leads to a corrected BFKL intercept as found earlier. The running coupling part of the kernel leads to a non-Regge term in the energy dependence of high energy hard scattering, as well as a Q2Q^2-dependent intercept.
