Description
Neutrino physics is a frontier and highly active interdisciplinary field in high energy physics. The Jiangmen Underground Neutrino Observatory (JUNO) is a medium-baseline, multi-purpose, large-scale neutrino experiment. The major goals are to determine the neutrino mass hierarchy by precisely measuring the energy spectrum of reactor neutrinos, and it is expected to achieve a 3sigma measurement after six years of data taking. So the energy resolution needs to reach 3% at 1 MeV, and energy scale precision has to be better than 1%.
After the experiment has commenced, it is crucial for JUNO to understand the experimental data, reduce systematic uncertainties, and suppress backgrounds. So this study develops a comprehensive IBD selection strategy based on the real latest dataset. Its main content is that utilizing the prompt and delayed signal characteristics of reactor neutrino (such as the time, distance, and energy features), thereby suppressing accidental backgrounds and improving selection efficiency.
