A double copy for asymptotic symmetries in the self-dual sector

M Campiglia, S Nagy - Journal of High Energy Physics, 2021 - Springer
A bstract We give a double copy construction for the symmetries of the self-dual sectors of
Yang-Mills (YM) and gravity, in the light-cone formulation. We find an infinite set of double …

Infinite-dimensional hierarchy of recursive extensions for all subn-leading soft effects in Yang-Mills

S Nagy, J Peraza, G Pizzolo - Journal of High Energy Physics, 2024 - Springer

extended phase space for Yang-Mills at null infinity, containing the asymptotic symmetries …

Gravitational Poisson brackets at null infinity compatible with smooth superrotations

M Campiglia, A Sudhakar - Journal of High Energy Physics, 2024 - Springer
A bstract Superrotations are local extensions of the Lorentz group at null infinity that have
been argued to be symmetries of gravitational scattering. In their smooth version, they can …

Radiative phase space extensions at all orders in r for self-dual Yang-Mills and gravity

S Nagy, J Peraza - Journal of High Energy Physics, 2023 - Springer
A bstract Working in the self-dual sector for Yang-Mills and gravity, we show how to construct
an extended phase space at null infinity, to all orders in the radial expansion. This formalises …

Renormalized electric and magnetic charges for O (rn) large gauge symmetries

J Peraza - Journal of High Energy Physics, 2024 - Springer
A bstract In this work we present the construction of a renormalized symplectic form on an
extended phases space where the higher order large gauge transformations (LGT) act …

Null hamiltonian yang–mills theory: Soft symmetries and memory as superselection

A Riello, M Schiavina - Annales Henri Poincaré, 2024 - Springer
Abstract Soft symmetries for Yang–Mills theory are shown to correspond to the residual
Hamiltonian action of the gauge group on the Ashtekar–Streubel phase space, which is the …

(rN) two-form asymptotic symmetries and renormalized charges

M Romoli - Journal of High Energy Physics, 2024 - Springer
A bstract We investigate\(\mathcal {O}\)(r N) asymptotic symmetries for a two-form gauge
field in four-dimensional Minkowski spacetime. By employing symplectic renormalization, we …

A deformed supersymmetric symmetry in the celestial conformal field theory

C Ahn - The European Physical Journal C, 2022 - Springer
By using the K-free complex bosons and the K-free complex fermions, we construct the N= 2
supersymmetric W∞ K, K algebra which is the matrix generalization of previous N= 2 …

Dynamical Edge Modes in Yang-Mills Theory

A Ball, L Ciambelli - arXiv preprint arXiv:2412.06672, 2024 - arxiv.org
We study the symplectic structure and dynamics of Yang-Mills theory in the presence of a
boundary. We introduce a decomposition of the fields on a Cauchy slice such that the …

The St\" uckelberg Path to Pure de Sitter Supergravity

S Bansal, S Nagy, A Padilla, I Zavala - arXiv preprint arXiv:2411.05710, 2024 - arxiv.org
We advance the study of pure de Sitter supergravity by introducing a finite formulation of
unimodular supergravity via the super-St\" uckelberg mechanism. Building on previous …
