Soft Algebra for SYM
Luis F. Alday, Andrew Strominger
Scattering amplitudes of particles in nonabelian gauge theories admit factorizations of the general form $\mathcal{A}_n \;=\; \mathcal{A}^{\rm soft}_n \times \mathcal{A}^{\rm h…
EVERY CFT HAS AN SYMMETRY
Andrew Strominger, Hongji Wei
Recently a one-parameter family of deformed soft symmetry algebras, denoted , acting on tree-level gravitational theories in…
Single-minus graviton tree amplitudes are nonzero
Alfredo Guevara, Alexandru Lupsasca, David Skinner +2
Single-minus tree-level -graviton scattering amplitudes are revisited. Often presumed to vanish, they are shown here to be nonvanishing for certain "half-collinear" configuratio…
Self-Dual Black Holes in Celestial Holography
Erin Crawley, Alfredo Guevara, Elizabeth Himwich +1
We construct two-dimensional quantum states associated to four-dimensional linearized rotating self-dual black holes in signature Klein space. The states are comprised of g…
An Integer Basis for Celestial Amplitudes
Jordan Cotler, Noah Miller, Andrew Strominger
We present a discrete basis of solutions of the massless Klein-Gordon equation in 3+1 Minkowski space which transform as sl(2,C) Lorentz/conformal primaries and descendants, and wh…
Cosmic ER=EPR in dS/CFT
Jordan Cotler, Andrew Strominger
In the dS/CFT correspondence, bulk states on global spacelike slices of de Sitter space are dual to (in general) entangled states in the tensor product of the dual CFT Hilbert spac…
