Neutrinoless double beta decay
The NEXT collaboration is looking for the neutrinoless double beta decay of the Xe-136 isotope. Its discovery might help explain the source of the asymmetry between matter and antimatter in the universe.
The NEXT experiment
The NEXT project is an international collaboration that looks for an hypothetical nuclear process called neutrinoless double-beta decay.
