Sensitivity of neutrinoless double beta decays from a combined analysis of ground and excited states

C. R. Ding, K. Han, S. B. Wang +1

Next-generation neutrinoless double-beta ($0\hat{I}½{\hat{I}}^2{\hat{I}}^2$) decay experiments, with projected half-life sensitivities approaching $10^{28}$ years, aim to probe the entire parameter space…
