Lattice Calculation of Short-Range Contributions to Neutrinoless Double-Beta Decay $\ddot{I}{€}^{-}\to \ddot{I}{€}^{+}ee$ at Physical Pion Mass

Peter Boyle, Felix Erben, Xu Feng +7

Neutrinoless double-beta ($0\hat{I}½{\hat{I}}^2{\hat{I}}^2$) decays provide an excellent probe for determining whether neutrinos are Dirac or Majorana fermions. The short-range matrix elements associated…
