FURTHER ANALYSIS OF THE BFKL EQUATION WITH MOMENTUM CUTOFFS

In this paper we investigate the effect of introducing transverse mome ntum cutoffs on the BFKL equation. We present solutions in moment spac e for various models of the BFKL kernel for different combinations of these cutoffs. We improve on previous calculations by using the full B FKL kernel (rather than simplified analytic approximations). The signi ficance of the next-to-leading or ''higher twist'' terms in the kernel are assessed. We find that, while these terms are negligible in the a bsence of cutoffs, introducing an infrared (IR) cutoff markedly enhanc es their significance.
