Symmetry Enhancement, SPT Absorption, and Duality in QED

Shai M. Chester, Zohar Komargodski

Quantum Electrodynamics in 2+1 dimensions (QED) with two Dirac fermions displays time reversal symmetry, nontrivial SPT phases and anomalies. The fate of this theory in its str…

The type IIA Virasoro-Shapiro amplitude in AdS CP from ABJM theory

Shai M. Chester, Tobias Hansen, De-liang Zhong

We consider tree level scattering of gravitons in type IIA string theory on to all orders in , which is dual to the stress tensor correlator in $U(…

The AdS Veneziano amplitude at small curvature

Luis F. Alday, Shai M. Chester, Tobias Hansen +1

We compute the AdS Veneziano amplitude for type IIB gluon scattering in to all orders in in a small curvature expansion. This is achieved by combining a di…

Integral constraints for super-Yang-Mills from a squashed sphere

Shai M. Chester, Ross Dempsey, Debaditya Pramanik +1

Supersymmetric localization and Ward identities have been used in the past several years to derive two integral constraints on the four-point function of the stress-tensor multiple…

Extremal couplings and gluon scattering in M-theory

Shai M. Chester, Rishi Mouland, Jesse van Muiden +1

We consider M-theory on the backgrounds AdS and AdS, which have fixed point locii AdS for . These…

Bootstrapping M-theory Orbifolds

Shai M. Chester, Silviu S. Pufu, Yifan Wang +1

We analyze correlation functions of flavor currents in a family of three-dimensional superconformal field theories, combining analytic bootstrap…
