Three-Flavoured Thermal Leptogenesis Without Tuning

Angus Spalding

We investigate thermal leptogenesis in an extension of the Type-I seesaw in which a real singlet scalar couples non-diagonally to the right-handed neutrinos. The interactions $-y_{…

Irreducible Gravitational Wave Background as a Particle Detector

Anish Ghoshal, Angus Spalding, Graham White

Beyond the standard model particles can imprint a temporary early matter-dominated epoch on a stochastic gravitational-wave background. For a freely propagating background whose pr…

Near-Resonant Thermal Leptogenesis

Angus Spalding

We study leptogenesis in the quasi-degenerate but non-resonant regime. Expanding the CP asymmetry parameter near degeneracy and imposing the conservative non-resonance condition th…
