Supersymmetry and anomalous dimensionalities of quasiparton operators in quantum chromodynamics
Bukhvostov A. P., Kuraev E. A., Lipatov L. N., Frolov G. V.
A class of quasiparton operators of arbitrary twist, which is closed with respect to the evolution equations, is introduced. For this class of operators, the evolution equations are Faddeev equations with a binary interaction. The role of the interaction is played by a matrix of anomalous dimensionalities of operators of twist 2. The subgroup of supersymmetry transformations is used to derive relations between the elements of the anomalous-dimensionality matrix in quantum chromodynamics.
