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…

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…
