Twist-2 Light-Ray Operators: Anomalous Dimensions and Evolution Equations1
The non–singlet and singlet anomalous dimensions of the twist–2 light–ray operators for unpolarized and polarized deep inelastic scattering are calculated in O(αs). We apply these results for the derivation of evolution equations for partition functions, structure functions, and wave functions which are defined as Fourier transforms of the matrix elements of the light-ray operators. Special cas...
متن کاملHigher Dimensional Operators or Large Extra Dimensions?
We deform gravity with higher curvature terms in four dimensions and argue that the non-relativistic limit is of the same form as the non-relativistic limit of the theories with large extra dimensions. Therefore the experiments that perform sub-millimeter tests of inverse-square law cannot distinguish the effects of large extra dimensions from the effects of higher dimensional operators. In oth...
متن کاملConformal constraints for anomalous dimensions of leading twist operators
Leading-twist operators have a remarkable property that their divergence vanishes in a free theory. Recently it was suggested that this property can be used for an alternative technique to calculate anomalous dimensions of leading-twist operators and allows one to gain one order in perturbation theory so that, i.e., two-loop anomalous dimensions can be calculated from one-loop Feynman diagrams,...

متن کاملThree loop anomalous dimensions of twist - 3 gauge operators in N = 4 SYM
We propose a closed expression for the three loop anomalous dimension of a class of twist-3 operators built with gauge fields and covariant derivatives. To this aim, we solve the long-range Bethe Ansatz equations at finite spin and provide a consistent analytical formula obtained assuming maximal transcendentality violation as suggested by the known one-loop anomalous dimension. The final resul...
