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

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

Physicists have set a new upper limit on the mass of neutrinos. And the finding could poke a big hole in the Standard Model ...

Neutrinos are one of the most enigmatic fundamental particles. The Standard Model of particle physics suggests that these ...

At the time, Pauli did not believe what he had proposed was true; he said, “I have done a terrible thing, I have postulated a particle that cannot be detected” 3. Neutrinos are emitted when protons ...

The KATRIN experiment in Germany nearly halved the maximum possible mass for neutrinos, setting it at 0.45 electron volts.

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

The international KArlsruhe TRItium Neutrino Experiment (KATRIN) at the Karlsruhe Institute of Technology (KIT) has once ...

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

One possible explanation for this excess, which appears in some extensions of the Standard Model of particle physics, is the existence of a fourth flavour of neutrino. Neutrinos of this “sterile” type ...

Constantinos G. Vayenas explores the roles of neutrinos, quantum mechanics, and special relativity in baryogenesis ...

The work was part of the MINERvA experiment, a particle physics experiment to study neutrinos.
