Abstract
We resum the recently calculated second order kernel of the BFKL equat ion. That kernel can be viewed as the sum of a conformally invariant p art and a running coupling part. The conformally invariant part leads to a corrected BFKL intercept as found earlier. The running coupling p art of the kernel leads to a non-Regge term in the energy dependence o f high energy hard scattering, as well as a Q(2)-dependent intercept.
