Cosmic string gravitational waves from global U(1) B−L symmetry breaking as a probe of the type I seesaw scale
Abstract In type I seesaw models, the right-handed neutrinos are typically super-heavy, consistent with the generation of baryon asymmetry via standard leptogenesis. Primordial gravitational waves of cosmological origin provides a new window to probe such high scale physics, which would otherwise be...
