Nuclear Matrix Elements for Double-Beta Decay
arXiv:1511.00074 · doi:10.1063/1.4915596
Abstract
Recent progress in nuclear-structure theory has been dramatic. I describe recent and future applications of ab initio calculations and the generator coordinate method to double-beta decay. I also briefly discuss the old and vexing problem of the renormalization of the weak nuclear axial-vector coupling constant "in medium" and plans to resolve it.
