$0\Nu\beta\beta$ and $2\Nu\beta\beta$ Nuclear Matrix Elements in the Interacting Boson Model with Isospin Restoration by Barea, J.; Kotila, J.; Iachello, F. is a scholarly article available to read on EtoBox.

What is $0\Nu\beta\beta$ and $2\Nu\beta\beta$ Nuclear Matrix Elements in the Interacting Boson Model with Isospin Restoration about?

We introduce a method for isospin restoration in the calculation of nuclear matrix elements (NME) for $0\nu\beta\beta$ and $2\nu\beta\beta$ decay within the framework of interacting boson model (IBM-2). With this method, we calculate NME for all processes of interest in $0\nu\beta^-\beta^-$, $2\nu\beta^-\beta^-$, and in $0\nu\beta^+\beta^+$, $0\nu\beta^+ EC^+$, $R0\nu ECEC$, $2\nu\beta^+\beta^+$, $2\nu\beta^+EC$, and $2\nu ECEC$. With this method, the Fermi (F) matrix elements for $2\nu\beta\beta$ vanish, and those for $0\nu\beta\beta$ are considerably reduced.
