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
A bstract Building on our proposal in [1], we present in detail the construction of the
extended phase space for Yang-Mills at null infinity, containing the asymptotic symmetries …

Self-dual cosmology

MC González, A Lipstein, S Nagy - Journal of High Energy Physics, 2024 - Springer
A bstract We construct cosmological spacetimes with a self-dual Weyl tensor whose
dynamics are described by conformally coupled scalars with only cubic self-interactions …

Carrollian Partition Functions and the Flat Limit of AdS

P Kraus, RM Myers - arXiv preprint arXiv:2407.13668, 2024 - arxiv.org
The formulation of the S-matrix as a path integral with specified asymptotic boundary
conditions naturally leads to the realization of a Carrollian partition function defined on 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 …
