Neutrinos are known to have tiny masses. A new result proclaims the subatomic particles to be even tinier still. Neutrinos are the only class of fundamental particle for which the mass, one of the ...

A large international research collaboration led by Dr. Kai-Qiang Lin and Professor John Lupton from the Institute of Experimental and Applied Physics at the University of Regensburg has been able to ...

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 ...

To understand neutrinos, it pays to be small-minded. The subatomic particles are so lightweight, they’re almost massless. They’re a tiny fraction of the mass of the next lightest particle, the ...

Scientists have made the most precise measurement yet of the electron's atomic mass. "It is a major technical improvement," said Edmund Myers, a physicist at Florida State University, who wrote an ...
