Origin of the Six-Gluon Amplitude in Planar N=4 Supersymmetric Yang-Mills Theory.

This work studies the maximally-helicity-violating six-gluon scattering amplitude in planar N=4 super-Yang-Mills theory at finite coupling when all three cross ratios are small, and presents conjectures for the all-order resummation of these anomalous dimensions.

The seven-gluon amplitude in multi-Regge kinematics beyond leading logarithmic accuracy

A bstractWe present an all-loop dispersion integral, well-defined to arbitrary logarithmic accuracy, describing the multi-Regge limit of the 2 → 5 amplitude in planar N=4$$ \mathcal{N}=4 $$ super

Analytic Result for a Two-Loop Five-Particle Amplitude.

The multi-Regge limit of the nonplanar terms, analyze its subleading power corrections, and analytically present the leading logarithmic terms are studied.

All-Order Amplitudes at any Multiplicity in the Multi-Regge Limit.

We propose an all-loop expression for scattering amplitudes in planar N=4 super Yang-Mills theory in multi-Regge kinematics valid for all multiplicities, all helicity configurations, and arbitrary

All two-loop MHV remainder functions in multi-Regge kinematics

A bstractWe introduce a method to extract the symbol of the coefficient of (2πi)2 of MHV remainder functions in planar N$$ \mathcal{N} $$ = 4 Super Yang-Mills in multi-Regge kinematics region

The four-loop remainder function and multi-Regge behavior at NNLLA in planar $ \mathcal{N} $ = 4 super-Yang-Mills theory

A bstractWe present the four-loop remainder function for six-gluon scattering with maximal helicity violation in planar $ \mathcal{N} $ = 4 super-Yang-Mills theory, as an analytic function of three

Form factors with two operator insertions and the principle of maximal transcendentality

We present the first calculations of two-point two-loop form factors (FFs) with a two identical operators insertion in maximally supersymmetric Yang-Mills theory. In this article, we consider the

Traintrack Calabi-Yaus from twistor geometry

We describe the geometry of the leading singularity locus of the traintrack integral family directly in momentum twistor space. For the two-loop case, known as the elliptic double box, the leading

Cluster adjacency and the four-loop NMHV heptagon

A bstractWe exploit the recently described property of cluster adjacency for scattering amplitudes in planar N=4$$ \mathcal{N}=4 $$ super Yang-Mills theory to construct the symbol of the four-loop

Cluster adjacency beyond MHV

A bstractWe explore further the notion of cluster adjacency, focussing on non-MHV amplitudes. We extend the notion of adjacency to the BCFW decomposition of tree-level amplitudes. Adjacency controls
