Large N anomalous dimensions for large operators in Leigh-Strassler deformed SYM
Robert de Mello Koch, Jeff Murugan, Nkululeko Nokwara
We study the large N anomalous dimensions of operators in a Leigh-Strassler deformation of N=4 super Yang-Mills theory. The operators that we study have a bare dimension of order N…
Restricted Schur Polynomials for Fermions and integrability in the su(2|3) sector
Robert de Mello Koch, Pablo Diaz, Nkululeko Nokwara
We define restricted Schur polynomials built using both fermionic and bosonic fields which transform in the adjoint of the gauge group U(N). We show that these operators diagonaliz…
On the refined counting of graphs on surfaces
Robert de Mello Koch, Sanjaye Ramgoolam, Congkao Wen
Ribbon graphs embedded on a Riemann surface provide a useful way to describe the double line Feynman diagrams of large N computations and a variety of other QFT correlator and scat…
Nonplanar integrability at two loops
Robert de Mello Koch, Garreth Kemp, Badr Awad Elseid Mohammed +1
In this article we compute the action of the two loop dilatation operator on restricted Schur polynomials that belong to the su(2) sector, in the displaced corners approximation. I…
Extremal vs. Non-Extremal Correlators with Giant Gravitons
Pawel Caputa, Robert de Mello Koch, Konstantinos Zoubos
We consider extremal and non-extremal three-point functions of two giant gravitons and one point-like graviton using Schur polynomials in N=4 super Yang-Mills theory and holographi…
A double coset ansatz for integrability in AdS/CFT
Robert de Mello Koch, Sanjaye Ramgoolam
We give a proof that the expected counting of strings attached to giant graviton branes in AdS_5 x S^5, as constrained by the Gauss Law, matches the dimension spanned by the expect…
Beyond the Planar Limit in ABJM
Robert de Mello Koch, Badr Awad Elseid Mohammed, Jeff Murugan +1
In this article we consider gauge theories with a U(N)X U(N) gauge group. We provide, for the first time, a complete set of operators built from scalar fields that are in the bi fu…
