摘要

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 AdS 5 × S 5 . Particularly, we explicitly obtain the structure functions for single-trace spin- 1 / 2 fermionic operators in the 20 * and 60 * irreducible representations of S U ( 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 S U ( 4 ) R . New important effects are found in comparison with the minimal twist ( τ = 3 ) case, and they are studied thoroughly.
