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…
Ultralight vector dark matter search using data from the KAGRA O3GK run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1800
Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating l…
Bounds on boosted dark matter from direct detection: The role of energy-dependent cross sections
Debjyoti Bardhan, Supritha Bhowmick, Diptimoy Ghosh +2
The recoil threshold of Direct Detection experiments limits the mass range of Dark Matter (DM) particles that can be detected, with most DD experiments being blind to sub-MeV DM pa…
