General Spin-1 Dynamics During Inflation: Microcausality Constraints and Cosmological Collider Signals
Trevor Cheung, Carlos Duaso-Pueyo, David Stefanyszyn +1
We construct the general theory of a spin-1 field propagating on an inflationary background consistent with scale invariance, rotations, Bunch-Davies conditions and microcausality.…

Massive Spinning Fields During Inflation: Feynman rules and correlator comparison
Trevor Cheung, David Stefanyszyn
We consider the dynamics of massive spinning fields during inflation and the resulting signatures in the cosmological correlators of inflaton perturbations computed in the Poincaré…
