In a Physical Review Letters study, the HOLMES collaboration has achieved the most stringent upper bound on the effective electron neutrino mass ever obtained using a calorimetric approach, setting a ...

Deep in the heart of the matter, some numbers don't add up. For example, while protons and neutrons are made of quarks, nature's fundamental building blocks bound together by gluons, their masses are ...

An experiment nearly two decades in the making has finally unveiled its measurements of the mass of the universe’s most abundant matter particle: the neutrino. The neutrino could be the weirdest ...

Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment carried out at the U.S. Department of Energy's Thomas Jefferson National ...

An experiment being built at the Gran Sasso laboratory in Italy could provide valuable insights into neutrino physics and the nature of dark matter. Ettore Fiorini of Milan University and colleagues ...

Physicist Björn Lehnert from the Lawrence Berkeley National Laboratory talks to Richard Blaustein about what a new precise measurement of the neutrino means for particle physics Weighty matters: ...

Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment has revealed the radius of the proton's mass that is generated by the ...
