Infinite-dimensional fermionic symmetry in supersymmetric gauge theories

Journal of High Energy Physics, 2021
We establish the existence of an infinite-dimensional fermionic symmetry in four-dimensional supersymmetric gauge theories by analyzing semiclassical photino dynamics in abelian N $$ \mathcal{N} $$ = 1 theories with charged matter.

Holographic symmetry algebras for gauge theory and gravity

Journal of High Energy Physics, 2021
All 4D gauge and gravitational theories in asymptotically flat spacetimes contain an infinite number of non-trivial symmetries. They can be succinctly characterized by generalized 2D currents acting on the celestial sphere.

The soft S $$ \mathcal{S} $$ -matrix in gravity

Journal of High Energy Physics, 2020
The gravitational S $$ \mathcal{S} $$ -matrix defined with an infrared (IR) cutoff factorizes into hard and soft factors. The soft factor is universal and contains all the IR and collinear divergences.

Self-dual black holes in celestial holography

Journal of High Energy Physics, 2023
We construct two-dimensional quantum states associated to four-dimensional linearized rotating self-dual black holes in (2, 2) signature Klein space. The states are comprised of global conformal primaries circulating on the celestial torus, the Kleinian ...

Perturbatively exact w 1+∞ asymptotic symmetry of quantum self-dual gravity

Journal of High Energy Physics, 2022
The infinite tower of positive-helicity soft gravitons in any minimally coupled, tree-level, asymptotically flat four-dimensional (4D) gravity was recently shown to generate a w 1+∞ asymptotic symmetry algebra. It is natural to ask whether this classical

Soft gravitons in the BFSS matrix model

Journal of High Energy Physics, 2023
BFSS proposed that asymptotically flat M-theory is dual to a large N limit of the matrix quantum mechanics describing N nonrelativistic D0-branes. Recent insights on the soft symmetries of any quantum theory of gravity in asymptotically flat space are ...

Black holes in Klein space

Journal of High Energy Physics, 2022
The analytic continuation of the general signature (1, 3) Lorentzian Kerr-Taub-NUT black holes to signature (2, 2) Kleinian black holes is studied.

State-operator correspondence in celestial conformal field theory

Journal of High Energy Physics, 2021
The bulk-to-boundary dictionary for 4D celestial holography is given a new entry defining 2D boundary states living on oriented circles on the celestial sphere.

Celestial amplitudes as AdS-Witten diagrams

Journal of High Energy Physics, 2022
Both celestial and momentum space amplitudes in four dimensions are beset by divergences resulting from spacetime translation and sometimes scale invariance.

Deforming soft algebras for gauge theory

Journal of High Energy Physics, 2023
Symmetry algebras deriving from towers of soft theorems can be deformed by a short list of higher-dimension Wilsonian corrections to the effective action.
