Higher-spin charges and the algebra in (A)dS
Lorenzo Di Giacomo, Maitá Micol, Daniele Pranzetti +1
We consider -dimensional asymptotically locally (anti-)de Sitter ((A)dS) spacetimes with boundary conditions allowing for gravitational flux. We construct an infinite to…
Mixed-helicity bracket of celestial symmetries
Daniele Pranzetti, Domenico Giuseppe Salluce
Celestial symmetries of gravity and gauge theory can be enhanced to a algebra and an -algebra respectively, when restricting to a single graviton/gluon helicity s…
Double-soft limit and celestial shadow OPE from charge bracket
Daniele Pranzetti, Domenico Giuseppe Salluce
The dual formulations of an infinite tower of tree-level soft theorems in asymptotically flat spacetimes for scattering amplitudes in the standard energy-momentum basis and for cor…
On the Definition of the Spin Charge in Asymptotically-Flat Spacetimes
Laurent Freidel, Seyed Faroogh Moosavian, Daniele Pranzetti
We propose a solution to a classic problem in gravitational physics consisting of defining the spin associated with asymptotically-flat spacetimes. We advocate that the correct asy…
On infinite symmetry algebras in Yang-Mills theory
Laurent Freidel, Daniele Pranzetti, Ana-Maria Raclariu
Similar to gravity, an infinite tower of symmetries generated by higher-spin charges has been identified in Yang-Mills theory by studying collinear limits or celestial operator pro…
A discrete basis for celestial holography
Laurent Freidel, Daniele Pranzetti, Ana-Maria Raclariu
Celestial holography provides a reformulation of scattering amplitudes in four dimensional asymptotically flat spacetimes in terms of conformal correlators of operators on the two…
