Scientists around the world are being kept in suspense by the negligible mass of neutrinos,subatomic particles that could be matter and antimatter at the same time. Now, researchers from the University of Tokyo, or in collaboration with a Spanish physicist,possess used one of the world's most powerful computers to analyse a special decay of calcium-48, whose life, and which lasts trillions of years,depends on the unknown mass of neutrinos. This advance will facilitate the detection of this rare decay in underground laboratories.
