abstract

We demonstrate that $CP-$violation in the Majorana mass matrices of the heavy neutrinos can generate a $CP-$asymmetric universe. The subsequent decay of the Majorana particles generates a lepton number asymmetry. During the electroweak phase transition the lepton asymmetry is converted into a baryon asymmetry, which survives down to this time.

Does thermal leptogenesis in a canonical seesaw rely on initial memory?

hep-ph · 2025-03-13 · unverdicted · novelty 7.0

Flavor projection effects in density-matrix equations permit misaligned asymmetry components from N2 and N3 to survive N1 washout in hierarchical seesaw leptogenesis, dividing parameter space into four regimes under low-energy neutrino constraints.

A Model of Annihilogenesis

hep-ph · 2026-04-30 · unverdicted · novelty 7.0

An explicit model generates the observed baryon asymmetry via annihilogenesis of right-handed neutrinos confined in false-vacuum pockets during a strong first-order phase transition, relaxing the usual light-neutrino-mass upper bound on the CP asymmetry.

$n \to K\ell$ and the baryon asymmetry of the universe

hep-ph · 2026-05-30 · conditional · novelty 5.0

In SMEFT, the (B-L)-violating decay n → K⁺ℓ⁻ appears at dimension seven while the conserving n → K⁻ℓ⁺ requires dimension ten and is accompanied by lower-dimensional (B+L)-violating modes, so n → Kℓ without modes like p → π⁰ℓ⁺ suggests (B-L) violation.
