The dipole form of the BFKL kernel in supersymmetric Yang--Mills theories

Abstract

The dipole (Möbius) representation of the colour singlet BFKL kernel in the next-to-leading order is found in supersymmetric Yang--Mills theories. Ambiguities of this form and its conformal properties are discussed.
