Celestial leaf amplitudes

Journal of High Energy Physics
Celestial amplitudes may be decomposed as weighted integrals of AdS3-Witten diagrams associated to each leaf of a hyperbolic foliation of spacetime. We show, for the Kleinian three-point MHV amplitude, that each leaf subamplitude is smooth except for the

The Schwinger point

Journal of High Energy Physics, 2019
The Sommerfield model with a massive vector field coupled to a massless fermion in 1+1 dimensions is an exactly solvable analog of a Bank-Zaks model.

An algebraic approach to the analytic bootstrap

Journal of High Energy Physics, 2017
We develop an algebraic approach to the analytic bootstrap in CFTs. By acting with the Casimir operator on the crossing equation we map the problem of doing large spin sums to any desired order to the problem of solving a set of recursion relations.

Quasinormal corrections to near-extremal black hole thermodynamics

Journal of High Energy Physics
Recent work on the quantum mechanics of near-extremal non-supersymmetric black holes has identified a characteristic T 3/2 scaling of the low temperature black hole partition function. This result has only been derived using the path integral in the near-

Unitarity and positivity constraints for CFT at large central charge

Journal of High Energy Physics, 2017
We consider the four-point correlator of the stress tensor multiplet in N = 4 $$ \mathcal{N}=4 $$ SYM in the limit of large central charge c ∼ N 2.

Crossing symmetry and Higher spin towers

Journal of High Energy Physics, 2017
We consider higher spin operators in weakly coupled gauge conformal field theories. Crossing symmetry of mixed scalar correlators relates different higher spin towers and we study the consequences for the spectrum and structure constants of higher spin ...

Proof of the graviton MHV formula using Plebański’s second heavenly equation

Journal of High Energy Physics
Self-dual spacetimes can be thought of as spacetimes containing only positive helicity gravitons. In this work we give a perturbiner expansion for self-dual spacetimes based on Plebański’s second heavenly equation. The expansion is naturally organized as
