Classical solitons in anti-self-dual Yang-Mills theory
Tristan McLoughlin
We study classical soliton solutions in split-signature anti-self-dual Yang-Mills theory. Using Zakharov's dressing method, we construct rational lump solitons, which are localised…
Probing weak chaos in super Yang-Mills and long-range spin chains
Pawel Caputa, Brian Creed, Rathindra Nath Das +2
We study signatures of quantum chaos in finite-loop truncations of the planar dilatation operator in the sector of super Yang-Mills and its -de…
Celestial amplitudes on electromagnetic backgrounds: T-duality from S-duality
Tristan McLoughlin, Nathan Moynihan, Andrea Puhm
What is the boundary holographic dual of S-duality for gauge theories in asymptotically flat space-times? Celestial amplitudes, by virtue of exhibiting holographic properties of th…
Celestial holography on Kerr-Schild backgrounds
Riccardo Gonzo, Tristan McLoughlin, Andrea Puhm
We explore the celestial holography proposal for non-trivial asymptotically flat backgrounds including the Coulomb field of a static and spinning point charge, their gravitational…
The SAGEX Review on Scattering Amplitudes, Chapter 11: Soft Theorems and Celestial Amplitudes
Tristan McLoughlin, Andrea Puhm, Ana-Maria Raclariu
The soft limits of scattering amplitudes have been extensively studied due to their essential role in the computation of physical observables in collider physics. The universal fac…
The SAGEX Review on Scattering Amplitudes
Gabriele Travaglini, Andreas Brandhuber, Patrick Dorey +35
This is an introduction to, and invitation to read, a series of review articles on scattering amplitudes in gauge theory, gravity, and superstring theory. Our aim is to provide an…
Chaotic spin chains in AdS/CFT
Tristan McLoughlin, Anne Spiering
We consider the spectrum of anomalous dimensions in planar supersymmetric Yang-Mills theory and its super-conformal Leigh-Strassler deformations. Th…
Quantum Chaos in Perturbative super-Yang-Mills Theory
Tristan McLoughlin, Raul Pereira, Anne Spiering
We provide numerical evidence that the perturbative spectrum of anomalous dimensions in maximally supersymmetric SU(N) Yang-Mills theory is chaotic at finite values of N. We calcul…
One-Loop Non-Planar Anomalous Dimensions in Super Yang-Mills Theory
Tristan McLoughlin, Raul Pereira, Anne Spiering
We consider non-planar one-loop anomalous dimensions in maximally supersymmetric Yang-Mills theory and its marginally deformed analogues. Using the basis of Bethe states, we comput…
Asymptotic Charges and Coherent States in QCD
Riccardo Gonzo, Tristan McLoughlin, Diego Medrano +1
We study the connection between asymptotic symmetries in non-Abelian gauge theories and the generalised coherent states following from the application to QCD of the Faddeev-Kulish…
Conformal higher spin scattering amplitudes from twistor space
Tim Adamo, Philipp Haehnel, Tristan McLoughlin
We use the formulation of conformal higher spin (CHS) theories in twistor space to study their tree-level scattering amplitudes, finding expressions for all three-point anti-MHV am…
Multi-Soft gluon limits and extended current algebras at null-infinity
Tristan McLoughlin, Dhritiman Nandan
In this note we consider aspects of the current algebra interpretation of multi-soft limits of tree-level gluon scattering amplitudes in four dimensions. Building on the relation b…
Conformal Higher Spin Theory and Twistor Space Actions
Philipp Haehnel, Tristan McLoughlin
We consider the twistor description of conformal higher spin theories and give twistor space actions for the self-dual sector of theories with spin greater than two that produce th…
Double-Soft Limits of Gluons and Gravitons
Thomas Klose, Tristan McLoughlin, Dhritiman Nandan +2
The double-soft limit of gluon and graviton amplitudes is studied in four dimensions at tree level. In general this limit is ambiguous and we introduce two natural ways of taking i…
Comments on World-Sheet Form Factors in AdS/CFT
Thomas Klose, Tristan McLoughlin
We study form factors in the light-cone gauge world-sheet theory for strings in AdS_5 x S^5. We perturbatively calculate the two-particle form factor in a closed su(2) sector to on…

We formulate a set of consistency conditions appropriate to worldsheet form factors in the massive, integrable but non-relativistic, light-cone gauge fixed AdS(5) x S**5 string the…
Conformal Anomaly for Amplitudes in N=6 Superconformal Chern-Simons Theory
Till Bargheer, Niklas Beisert, Florian Loebbert +1
Scattering amplitudes in three-dimensional N=6 Chern-Simons theory are shown to be non-invariant with respect to the free representation of the osp(6|4) symmetry generators. At tre…
New Relations for Three-Dimensional Supersymmetric Scattering Amplitudes
Till Bargheer, Song He, Tristan McLoughlin
We provide evidence for a duality between color and kinematics in three-dimensional supersymmetric Chern-Simons matter theories. We show that the six-point amplitude in the maximal…
A light-cone approach to three-point functions in AdS_5 x S^5
Thomas Klose, Tristan McLoughlin
We consider worldsheet correlation functions for strings in AdS_5 x S^5 using a light-cone gauge for the worldsheet theory. We compute the saddle-point approximation to three-point…
