The quest to identify the nature of the neutrino’s alter ego is heating up
Physicists are trying to see if the particle’s matter and antimatter versions are the same
ANTIMATTER MYSTERY Physicists suspect that the neutrino may be its own antiparticle. Experiments such as GERDA (shown) are attempting to determine whether that hunch is correct by searching for a rare type of nuclear decay.
