Seminar Title: The Quest for Cogenesis Speaker: Prof. Wanzhe Feng 冯万哲 (Tianjin University) Time: 10:30 (Beijing Time), Monday, 2020-9-7 Zoom: https://zoom.us/j/2151583083 Place: R319, TPD, IHEP Zoom ID:2151583083 
Abstract: Cogenesis is usually referred to as a mechanism simultaneously causing baryo- (or lepto-) genesis plus the generation of dark matter. Moreover, elegant models can also explain more puzzles in the universe, e.g., the hierarchy problem, the tiny neutrino masses, etc. Cogenesis models usually produce asymmetric dark matter such that O(1) GeV dark matter candidate(s) are predicted, and thus the amount of dark matter and visible matter are of the same order is also automatically explained. In this talk I will present two cogenesis models, aiming to capture the main theme of this direction. |
