Neutrinos are among the most enigmatic particles in the universe. They are omnipresent yet interact extremely rarely with ...

Chief among the mysteries is their mass—an elusive property that has defied direct measurement for decades.KATRIN experiment ...

A new measurement finds the universe's teensiest particles weigh no more than one-millionth the mass of an electron.

Scientists from the KATRIN experiment have achieved the most precise upper limit ever recorded for the mass of the mysterious ...

New data establish an upper limit of 0.45 eV/c2 (equivalent to 8 x 10-37 kilograms) for the neutrino mass. KATRIN measures neutrino mass in the laboratory using a model-independent method.

It is no heavier than 0.45 electron volts (eV) — less than one-millionth the mass of an electron, the next-lightest known ...

New research claims that a super-powerful neutrino may have originated from an exploding primordial black hole. Now how long ...

Scientists trying to discover the elusive mass of neutrinos, tiny "ghost particles" that could solve some of the universe's ...

Scientists are inching closer to uncovering the mass of ghost particles, a mystery that has remained unsolved for decades.

A new estimate of the ghostly particle’s maximum possible mass brings physicists a tad closer to understanding the universe.
