#Neutrinos

Neutrinos are among the most abundant particles in the universe, but they are also among the most elusive. Nearly massless, they are produced by nuclear reactions in the sun, exploding stars, particle accelerators and even the decay of radioactive…

In the early Universe, neutrinos interacted strongly with other matter before some of them "decoupled." The heaviest of these decoupled neutrinos may be the solution to the matter-antimatter cosmic mystery.

A new study published in Physical Review Letters by the IceCube Collaboration reports evidence that the energy spectrum of astrophysical neutrinos is not a simple straight line.

Despite being the most abundant particles in the universe, neutrinos are notoriously difficult to detect. Could launching a space-based detector close to the sun change that?

New analyses by the IceCube observatory could help scientists understand where neutrinos form and what is producing them

Neutrinos pass through the entire planet without stopping. They travel billions of light-years from colliding black holes and exploding stars without being absorbed or deflected, arriving intact and pointing straight…

In the exotic world of particle physics, neutrinos may be the most mysterious members. They rarely interact with other matter, have almost no mass, and have no electrical charge. These characteristics make them extremely difficult to study.…

Neutrinos are very difficult to detect. And when they are detected, pinpointing their sources is likewise difficult. New research shows that the most energetic neutrino ever detected must have had an extraordinarly energetic source.…

Neutrinos have mass — yet they never flip between left- and right-handed states the way every other massive particle does. The most logical fix is Paul Dirac's: invisible right-handed neutrinos that interact with nothing whatsoever. The math works.…

An international team combining two major neutrino experiments has uncovered stronger evidence that neutrinos and antimatter don’t behave as perfect mirror images.…
