Right-Handed Neutrino Production by an Axion-like Inflaton: Implications for Leptogenesis
Weiyi Deng, Chengcheng Han, Wuzhou Yin +1
We study heavy right-handed neutrino production induced by a derivative coupling to an axion-like inflaton and its implications for non-thermal leptogenesis. We develop a unified t…

Probing Non-Thermal Gravitinos Through Large-Scale Structure Observations
Weiyi Deng, Liyuan Guo, Chengcheng Han +1
We investigate the effects of non-thermally produced dark matter on large-scale structure formation, focusing on the gravitino dark matter. Our analysis shows that large-scale stru…
