“Analysis of the full data set gained from this grand project will allow for estimating the effective electron neutrino mass close to the projected value of 0.3 eV at 90% confidence level.

Researchers from the KATRIN (Karlsruhe Tritium Neutrino) experiment report the most precise measurement of the upper mass limit of the neutrino to date, establishing it as 0.45 electron volts (eV ...

It seeks to constrain the neutrino’s mass by looking at the energy spectrum of electrons and electron antineutrinos emitted by decaying tritium, a radioactive isotope of hydrogen. As detailed in ...

Physicists have scaled down the maximum possible mass of an elusive "ghost particle" called a neutrino to at least one-millionth the weight of an electron. The revision takes scientists one more ...

Based in Karlsruhe, Germany, KATRIN studies an antimatter version of neutrino known as an electron antineutrino. The researchers observed radioactive decays of tritium, a heavy variety of hydrogen.

It is no heavier than 0.45 electron volts (eV) — less than one-millionth the mass of an electron, the next-lightest known particle at 511,000 eV. The results were described on 10 April in Science 1.

have announced the most precise upper limit yet on the neutrino’s mass. Thanks to new data and upgraded techniques, the new limit – 0.45 electron volts (eV) at 90% confidence – is half that of the ...

In the second instalment of a series to mark the 10th anniversary of the Future Science Prize, Victoria Bela looks at Professor Kam-Biu Luk’s experimental discovery of a new type of neutrino ...

In a paper published in Nature this week, the scientists in charge of KM3Net discuss how they detected the signature of the most powerful neutrino that science has ever seen. KM3Net is not a ...

The designer Conner Ives hoped to do some good with his “Protect the Dolls” T-shirt. Worn by celebrities, and sold out online, the shirts are raising money for a trans cause. By Alisha ...
