      报告题目:Cosmological Signatures of Neutrino Seesaw报 告 人:韩成成 (Sun Yet-sen University)报告时间:2025年1月8日14:00 报告地点:物理楼W218内容摘要:The tiny neutrino masses are most naturally explained by the seesaw mechanism through singlet right-handed neutrinos, which can further explain the matter-antimatter asymmetry in the universe. We propose a new approach to study cosmological sign...
