A New Twist on Spinning (A)dS Correlators
Daniel Baumann, Grégoire Mathys, Guilherme L. Pimentel +1
Massless spinning correlators in cosmology are extremely complicated. In contrast, the scattering amplitudes of massless particles with spin are very simple. We propose that the re…
Light-ray sum rules and the c-anomaly
Thomas Hartman, Grégoire Mathys
In a four-dimensional quantum field theory that flows between two fixed points under the renormalization group, the change in the conformal anomaly has been related to the ave…
Impossible Symmetries and Conformal Gravity
Kurt Hinterbichler, Austin Joyce, Grégoire Mathys
We explore the physics of relativistic gapless phases defined by a mixed anomaly between two generalized conserved currents. The gapless modes can be understood as Goldstone modes…
