Boundary Actions and Loop Groups: A Geometric Picture of Gauge Symmetries at Null Infinity
Silvia Nagy, Javier Peraza, Giorgio Pizzolo
In previous work arXiv:2407.13556, we proposed an extended phase space structure at null infinity accommodating large gauge symmetries for sub-leading soft theorems in Yang-Mil…
Homotopy kinematic algebras at null infinity
Felipe Díaz-Jaramillo, Silvia Nagy, Giorgio Pizzolo
We present the first formulation of a homotopy algebra adapted to a expansion near future null infinity (). Focusing on self-dual Yang-Mills theory in Bondi co…
Stückelberg path to pure de Sitter supergravity
Sukŗti Bansal, Silvia Nagy, Antonio Padilla +1
We advance the study of pure de Sitter supergravity by introducing a finite formulation of unimodular supergravity via the super-Stückelberg mechanism. Building on previous works,…
Infinite-dimensional hierarchy of recursive extensions for all sub-leading soft effects in Yang-Mills
Silvia Nagy, Javier Peraza, Giorgio Pizzolo
Building on our proposal in arXiv:2405.06629, we present in detail the construction of the extended phase space for Yang-Mills at null infinity, containing the asymptotic symmetrie…
A General Hierarchy of Charges at Null Infinity via the Todd Polynomials
Silvia Nagy, Javier Peraza, Giorgio Pizzolo
We give a general procedure for constructing an extended phase space for Yang-Mills theory at null infinity, capable of handling the asymptotic symmetries and construction of charg…
Convolutional double copy in (Anti) de Sitter space
Qiuyue Liang, Silvia Nagy
The double copy is a remarkable relationship between gauge theory and gravity that has been explored in a number of contexts, most notably scattering amplitudes and classical solut…
