Their mass is extremely low, but how light are neutrinos really? A collaboration comprising German and international research groups has optimized its experiments to determine the mass of these "ghost ...

Of all the known particles in the universe, only photons outnumber neutrinos. Despite their abundance, however, neutrinos are hard to catch and inspect, as they interact with matter only very weakly.

The humble neutrino, an elusive subatomic particle that passes effortlessly through normal matter, plays an outsized role among the particles that comprise our universe. To fully explain how our ...

Neutrinos are tiny particles that barely interact with anything. Trillions of them pass through your body every second, yet you’ll never notice. They have no electric charge and barely any mass. Still ...

Humble neutrinos — electrically neutral particles that glide through the universe, unaffected by the forces of nature — have helped to shape the cosmos. They play a role in nuclear fusion, radioactive ...

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 ...

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 ...

As I am sure all of you know, the 2015 Nobel Prize for Physics was awarded yesterday to Arthur McDonald and Takaaki Kajita “for the discovery of neutrino oscillations, which shows that neutrinos have ...
