Physicists Unlock New Path to Weighing the Universe’s “Ghost Particle”

Silver-110’s decay reveals a promising path to measure antineutrino mass. New data could reshape future neutrino studies. Neutrinos and antineutrinos are fundamental particles that possess mass, although their exact value remains unknown. Recent high-precision atomic mass measurements carried out at the Accelerator Laboratory of the University of Jyväskylä in Finland suggest that the beta decay [...]
