Resonant Forbidden Leptogenesis

by Dr Shaoping Li (李少平） (Osaka University)

Sunday 15 Jun 2025, 10:00 → 11:00 Asia/Shanghai

5#/6th-603 - Meeting Room 603 (Science Building)

Abstract:

Finite-temperature effects open more opportunities to explain the baryon asymmetry  of the universe in minimal models beyond the standard model (SM). In this talk, I will introduce the  forbidden CP asymmetry that is generated via soft-lepton resummation at finite temperatures  and has a SM-predicted resonant enhancement. It features leptogenesis at the electroweak  scale that is accessible at colliders, and dark matter cogenesis in the early universe.
