We review aspects of twistor theory, its aims and achievements spanning the last five
decades. In the twistor approach, space–time is secondary with events being derived …

The classical double copy relates exact solutions of gauge, gravity, and other theories.
Although widely studied, its origins and domain of applicability have remained mysterious. In …

A bstract Carrollian holography aims to express gravity in four-dimensional asymptotically
flat spacetime in terms of a dual three-dimensional Carrollian CFT living at null infinity …

Recently, spin-one wave functions in four dimensions that are conformal primaries of the
Lorentz group SL (2, C) were constructed. We compute low-point, tree-level gluon scattering …

We give an explicit recursive formula for the all ℓ-loop integrand for scattering amplitudes
in\(\mathcal {N}= 4\) SYM in the planar limit, manifesting the full Yangian symmetry of the …

A bstract This note addresses the problem of spurious poles in gauge-theoretic scattering
amplitudes. New twistor coordinates for the momenta are introduced, based on the concept …

We propose a dual formulation for the S Matrix of\(\mathcal N\)= 4 SYM. The dual provides a
basis for the “leading singularities” of scattering amplitudes to all orders in perturbation …

Dual superconformal invariance has recently emerged as a hidden symmetry of planar
scattering amplitudes in Script N= 4 super Yang-Mills theory. This symmetry can be made …

A bstract Analytic continuation from Minkowski space to (2, 2) split signature spacetime has
proven to be a powerful tool for the study of scattering amplitudes. Here we show that, under …
