Three-nucleon lepton-number-violating potentials in chiral EFT and their matrix elements in light nuclei

Graham Chambers-Wall, Justin Lieffers, Garrett B. King +4

We derive the three-nucleon neutrinoless double beta decay potential in $\hat{I}”$-full chiral effective field theory through next-to-next-to-next-to leading order in Weinberg's power co…
