Open AccessWilson loop duality and OPE for super form factors of half-BPS operators
We propose a dual Wilson loop description for the MHV super form factors of half-BPS operators in planar N

Open AccessFishnet four-point integrals: integrable representations and thermodynamic limits
We consider four-point integrals arising in the planar limit of the conformal “fishnet” theory in four dimensions. They define a two-parameter family of higher-loop Feynman integrals, which extend the series o...

Open AccessThree-point functions at strong coupling in the BMN limit
We consider structure constants of single-trace operators at strong coupling in planar N\( \mathcal{N} \) = 4 SYM theory using the hexagon formalism. We concentrate on heavy-heavy- light correlators where the hea...

Open AccessHexagons and correlators in the fishnet theory
We investigate the hexagon formalism in the planar 4d conformal fishnet theory. This theory arises from N ...

Open AccessABJM flux-tube and scattering amplitudes
There is a number of indications that scattering amplitudes in the Aharony-Bergman-Jafferis-Maldacena theory might have a dual description in terms of a holonomy of a supergauge connection on a null polygonal ...

Article
Open AccessAsymptotic four point functions
We initiate the study of four-point functions of large BPS operators at any value of the coupling. We do it by casting it as a sum over exchange of superconformal primaries and computing the structure constant...

Open AccessContinuum limit of fishnet graphs and AdS sigma model
We consider the continuum limit of 4d planar fishnet diagrams using integrable spin chain methods borrowed from the ...

Open AccessOPE for all helicity amplitudes II. Form factors and data analysis
We present the general flux tube integrand for MHV and non-MHV amplitudes, in planar N ...

Open AccessOPE for all helicity amplitudes
We extend the Operator Product Expansion (OPE) for scattering amplitudes in planar N ...

Open AccessAdjoint BFKL at finite coupling: a short-cut from the collinear limit
In the high energy Regge limit, the six gluons scattering amplitude is controlled by the adjoint BFKL eigenvalue and impact factor. In this paper we determine these two building blocks at any value of the ’t H...

Open AccessSpace-time S-matrix and flux-tube S-matrix IV. Gluons and fusion
We analyze the pentagon transitions involving arbitrarily many flux-tube gluonic excitations and bound states thereof in planar ...

Open AccessSpace-time S-matrix and flux-tube S-matrix III. The two-particle contributions
We consider light-like Wilson loops with hexagonal geometry in the planar limit of N ...

Open AccessSpace-time S-matrix and flux tube S-matrix II. Extracting and matching data
We elaborate on a non-perturbative formulation of scattering amplitudes/null polygonal Wilson loops in planar \( \mathcal{N} \) ...
