BFKL Evolution as a Communicator Between Small and Large Energy Scales

Abstract

We analyze, in leading and next to leading order of BFKL, a possible influence of Beyond the Standard Model (BSM) effects on the structure of the discrete pomeron states. We show that the eigenvalues of the states which contribute significantly to the gluon density in the observable region are substantially modified by BSM effects irrespective of the assumptions about the infrared boundary conditions. We also develop a physically motivated heuristic model of the infrared boundary condition which determines the gluon structure function and argue, using this model, that the analysis of the present and future low-$x$ data could allow the detection of a supersymmetry scale in the multi-TeV range.

v3 contains additional explanations,v2 is identical to v1 with 3 superfluous figures removed, arXiv admin note: substantial text overlap with arXiv:1109.0432
