Operator Mixing in N = 4 Sym: the Konishi Anomaly Revisited
In the context of the superconformal N = 4 SYM theory the Konishi anomaly can be viewed as the descendant K10 of the Konishi multiplet in the 10 of SU(4), carrying the anomalous dimension of the multiplet. Another descendant O10 with the same quantum numbers, but this time without anomalous dimension, is obtained from the protected half-BPS operator O20′ (the stress-tensor multiplet). Both K10 ...
متن کاملTwo - Loop Polygon Wilson Loops in N = 4 SYM
We compute for the first time the two-loop corrections to arbitrary n-gon lightlike Wilson loops in N = 4 supersymmetric Yang-Mills theory, using efficient numerical methods. The calculation is motivated by the remarkable agreement between the finite part of planar six-point MHV amplitudes and hexagon Wilson loops which has been observed at two loops. At n = 6 we confirm that the ABDK/BDS ansat...
متن کاملWrapping at four loops in N = 4 SYM
We present the planar four-loop anomalous dimension of the composite operator tr(φ [Z,φ]Z) in the flavour SU(2) sector of the N = 4 SYM theory. At this loop order wrapping interactions are present: they give rise to contributions proportional to ζ(5) increasing the level of transcendentality of the anomalous dimension. In a sequel of this paper all the details of our calculation will be reporte...
متن کاملYangian Symmetry at Two Loops for the su ( 2 | 1 ) Sector of N = 4 SYM
We present the perturbative Yangian symmetry at next-to-leading order in the su(2|1) sector of planar N = 4 SYM. Just like the ordinary symmetry generators, the bi-local Yangian charges receive corrections acting on several neighboring sites. We confirm that the bi-local Yangian charges satisfy the necessary conditions: they transform in the adjoint of su(2|1), they commute with the dilatation ...
متن کاملRelaxed super self - duality and N = 4 SYM at two loops
A closed-form expression is obtained for a holomorphic sector of the two-loop low-energy effective action for the N = 4 super Yang-Mills theory on its Coulomb branch where the gauge group SU(N) is spontaneously broken to SU(N−1)×U(1) and the dynamics is described by a single Abelian N = 2 vector multiplet. In the framework of the background-field method, this holomorphic sector is singled out b...
