Resumen
The role of local higher-twist (τ>3) spin-1/2 fermionic operators of the strongly coupled N=4 supersymmetric Yang-Mills theory on the symmetric and antisymmetric deep inelastic scattering structure functions is investigated. The calculations are carried out in terms of the duality between N=4 SYM theory and type IIB supergravity on AdS5×S5. Particularly, we explicitly obtain the structure functions for single-trace spin-1/2 fermionic operators in the 20∗ and 60∗ irreducible representations of SU(4)R, corresponding to twists 4 and 5, respectively. We also calculate the contributions of other single-trace spin-1/2 fermionic operators in the 4, 20 and 60 irreducible representations of SU(4)R. New important effects are found in comparison with the minimal twist (τ=3) case, and they are studied thoroughly.
