Amplitude's positivity vs. subluminality: Causality and Unitarity Constraints on dimension 6 & 8 Gluonic operators in the SMEFT
Diptimoy Ghosh, Rajat Sharma, Farman Ullah
We derive the causality and unitarity constraints on dimension 6 and dimension 8 Gluon field strength operators in the Standard Model Effective Field Theory (SMEFT). In the first p…
Gravitation Wave signal from Asteroid mass Primordial Black Hole Dark Matter
Diptimoy Ghosh, Arvind Kumar Mishra
Primordial Black Holes (PBHs) in the mass range g are currently unconstrained, and can constitute the full Dark Matter (DM) density of the universe. Motivate…
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…
Probing the initial state of inflation: analytical structure of cosmological correlators
Diptimoy Ghosh, Amartya Harsh Singh, Farman Ullah
We study the analytic structure of in-in correlation functions in a deSitter background. The aim of this study is to probe the initial conditions for inflation through the features…
