Singularities in Cosmological Loop Correlators II : Non Local Interactions and Flat Space limits
Elaf Ansari, Supritha Bhowmick, Diptimoy Ghosh
Non-local interactions naturally arise in the ADM formalism after solving the constraint equations and substituting their solutions back into the action. However, the effects of th…

Singularities in Cosmological Loop Correlators
Supritha Bhowmick, Mang Hei Gordon Lee, Diptimoy Ghosh +1
In this work we perform a systematic study of the singularity structure of inflationary correlations at 1-loop. We explicitly compute a few diagrams and find a pattern emerging in…

Bispectrum at 1-loop in the Effective Field Theory of Inflation
Supritha Bhowmick, Diptimoy Ghosh, Farman Ullah
In this paper we compute 1-loop corrections to the bispectrum in the decoupling limit of the Effective Field Theory of Inflation (EFToI). We regulate the divergences by employing d…
