Probing thermal leptogenesis and dark matter through primordial gravitational waves from a supercooled universe
Peter Athron, Satyabrata Datta, Zhao-Yang Zhang
We explore the cosmological dynamics of a supercooled first-order phase transition in the classically conformal extension of the Standard Model, where radiative symmet…
Gravitational Wave Spectral Shapes as a probe of Long Lived Right-handed Neutrinos, Leptogenesis and Dark Matter: Global versus Local B-L Cosmic Strings
Satyabrata Datta, Anish Ghoshal, Angus Spalding +1
The scale of the seesaw mechanism is typically much larger than the electroweak scale. This hierarchy can be naturally explained by symmetry, which after spontaneous s…
Multifaceted Supercooling: From PTA to LIGO
Satyabrata Datta, Rome Samanta
Supercooled phase transitions, as predicted, e.g., in near-conformal and confining extensions of the Standard Model (SM), are established sources of strong stochastic gravitational…
Complementarity between Cosmic String Gravitational Waves and long-lived particle searches in a laboratory
Satyabrata Datta, Ambar Ghosal, Anish Ghoshal +1
Cosmic strings are powerful witnesses to cosmic events including any period of early matter domination. If such a period of matter domination was catalysed by metastable, long-live…
