The emission of beta radiation provides evidence ... Each of particles in the standard model has an associated antiparticle. When a particle and antiparticle combine to ‘annihilate’ each ...

The Standard Model (SM) predicts the distribution of emission angles for the beta particle and neutrino, and any observed difference would reveal new aspects of the weak nuclear force. The team ...

Precision studies of the beta disintegration of atomic nuclei provide stringent tests of the weak nuclear force, encoded in the Standard Model ... existing high-energy particle colliders.

The observation of neutrinoless double beta ... particle in the universe but many of its properties, including its mass, are still shrouded and not well explained by the Standard Model." ...
