Description
In the search for neutrinoless double beta decay (0νββ) experiments, common data analysis methods include the traditional counting method within a region of interest, while energy spectrum fitting methods are used in some experiments like KamLAND-Zen. These two types of methods differ in their sensitivities to the 0νββ half-life.
Simulations are performed to quantify such differences, using the background conditions at the China Jinping Underground Laboratory (CJPL). The results of the simulation indicate that the fitting method would yield a higher sensitivity than the counting method by a factor of 1.25. This study discusses the source of these differences, and the conclusions can provide benefits for future 0νββ experiments in selecting data processing methods.
