The Neutrino group of QMRC will develop the NνDEx experiment at China Jinping Underground Laboratory (CJPL), as well as related high precision theoretical calculations, to search for neutrinoless double beta decay and distinguish its mechanism. Our final goal is to find new physics beyond the standard model, and to answer questions such as the nature of neutrino and the matter-antimatter asymmetry of early universe.
We will develop an experiment: No neutrino Double-beta Experiment (NνDEx) to be located in CJPL. The NνDEx project plans to take advantage of the recent development of the topmetal silicon sensors and construct a high pressure 82SeF6 gas gainless TPC, in order to achieve high sensitivity to neutrinoless double beta decay, by having high decay Q-value, high energy resolution, and the ability to distinguish signal and background via their different geometric characteristics.
With state-of-art nuclear structure theory, we calculate various observables of double beta decay, such as half-lives, electron spectra and their angular distribution.
We also actively engage in studies such as neutrino oscillations and new physics beyond standard model.
