Today, the Majorana Collaboration has announced the results of an exciting new research endeavor: the search for neutrinoless double-beta decay. This type of decay may provide important insight into the behavior of neutrinos, particles that are essential to our understanding of the universe. The collaboration’s results were obtained using an array of highly sensitive detectors located in an underground laboratory, and suggest that neutrinoless double-beta decay has not been observed. This finding places significant constraints on the neutrino’s mass, a key property of these particles.
