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 DÃaz-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
SukÅti 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,…
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…
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…
