Bootstrapping one-loop inflation correlators with the spectral decomposition
Bootstrapping one-loop inflation correlators with the spectral decomposition
Phenomenological studies of cosmological collider physics in recent years have identified many 1-loop inflation correlators as leading channels for discovering heavy new particles around or above the inflation scale. However, complete analytical results for these massive 1-loop correlators are currently unavailable. In this work, we embark on a program of …
