Technology is being pushed to its very limits. The upgrades to the Large Hadron Collider (LHC) at CERN slated for the next ...

Researchers established the maximum possible neutrino mass at 0.45 electron volts (eV), while the electron mass surpasses this value by a million times. The new precision threshold from this ...

2023 Inelastic electron scattering in tritium gas and ppm-precise energy ... by the inner wire electrode and set-up of the condensed krypton source at the neutrino mass experiment KATRIN [pdf] Dr.

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 ...

This cutting-edge technology allows for unprecedented precision in direct neutrino mass measurements. With the current data from the KATRIN experiment, an upper limit of 0.45 electron volt/c 2 ...

experiment report the most precise measurement of the upper mass limit of the neutrino to date, establishing it as 0.45 electron volts (eV) — less than one-millionth the mass of an electron. Neutrinos ...

Credit: Markus Breig, KIT Scientists from the KATRIN experiment have achieved the most precise upper limit ever recorded for the mass of the mysterious neutrino – clocking in at less than 0.45 ...

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.

The Ramsauer technique has been used to measure the absolute total electron-helium-atom scattering cross section as a function of electron energy from 0.30 to 28 eV ...

Three types or "flavours" of neutrino exist: the electron neutrino, the muon neutrino and the tau neutrino. But it seems that neutrinos are the chameleons of the particle world: they can change from ...

Seminars in italics are upcoming.

and therefore has the same mass as the electron but the opposite charge. When a nucleus undergoes positron decay, the result is a new nuclide with 1 fewer proton and 1 more neutron, as well as the ...
