Enhancing Sensitivity in Ge-Based Rare-Event Physics Experiments through Underground Crystal Growth and Detector Fabrication

Autor: Mei, Dongming

The cosmogenic production of long-lived isotopes such as $^{3}$H,$^{55}$Fe, $^{60}$Co, $^{65}$Zn, and $^{68}$Ge poses a significant challenge as a source of background events in Ge-based dark matter (DM) and neutrinoless double-beta decay ($0\nu\beta

The Decay Q Value of Neutrinoless Double Beta Decay

Autor: Mei, Dongming, Wei, Wenzhao

An earlier publication "The implication of the atomic effects in neutrinoless double beta (0$\nu\beta\beta$) decay" written by Mei and Wei has motivated us to compare the decay Q value ($Q_{\beta\beta}$) derived from the decay of the parent nucleus t
