Pinning Down a Ghost Particle: Neutrino Mass Measured with Unprecedented Precision

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 electron volts. This breakthrough not only tightens the constraints on one of the universe’s most elusive particles but also challenges and extends the boundaries of the Standard [...]

Neutrinos’ maximum possible mass shrinks further

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

KATRIN at KIT Sets New Record, Establishing an Upper Limit of 0.45 eV/c² for Neutrino Mass

KATRIN at KIT Sets New Record, Establishing an Upper Limit of 0.45 eV/c² for Neutrino Mass (IN BRIEF) The KATRIN experiment at the Karlsruhe Institute of Technology has set a new upper limit for the mass of neutrinos at 0.45 eV/c², a record-breaking achievement that refines our understanding of these elusive particles. Neutrinos, which scarcely interact with matter, influence the formation of galaxies and signal the presence of unknown physical …

Astroparticle Physics Breakthrough: Neutrino Mass Determined to be Below

Neutrinos are one of the most elusive and enigmatic particles in the universe. They are everywhere, pervading the cosmos, yet they engage with matter in a way that is almost negligible. This peculiar behavior makes them quintessentially fascinating, compelling scientists to unravel their mysteries. In the universe’s grand design, neutrinos significantly influence large-scale structures, such as galaxy formations, while in the realm of particle p…

A neutrino is an elementary particle that is produced in stars and nuclear reactors. It travels at the speed of light and has virtually no interaction with matter. There are three categories of neutrinos: electron, muon, and tau neutrinos. The ability of a neutrino to change its “flavors” indicates that it has mass, but the exact value of this mass has not yet been established.... The post The KATRIN experiment has brought scientists closer to d…

"Ghost particles": physicists have managed to further narrow down the mass of neutrinos thanks to the world's unique KATRIN experiment in Karlsruhe. Thus, "these elementary particles, which are important for cosmology, weigh less than 0.45 electron volts – that is less than one millionth of the mass of an electron, as the team reports in Science. Because this measured value is independent of cosmological assumptions, it can help to better unders…
