Discrepancy between experimental and theoretical β-decay rates resolved from first principles

P Gysbers, G Hagen, JD Holt, GR Jansen, TD Morris… - Nature Physics, 2019 - nature.com
The dominant decay mode of atomic nuclei is beta decay (β-decay), a process that changes
a neutron into a proton (and vice versa). This decay offers a window to physics beyond the …
