tau neutrino

noun

, Physics.

1. a hypothetical type of neutrino that would obey a conservation law together with the tau lepton, with the total number of tau leptons and tau neutrinos minus the total number of their antiparticles remaining constant.

1. physics a type of neutrino associated with tau particles

tau neutrino

/ tou,tô /

1. A type of neutrino associated with the tau particle, often created in particle interactions involving tau particles (such as the decay of these particles). The tau neutrino has a mass of zero or near zero, and has no electric charge.

From Science Magazine

It says that everything in the Universe is made up of a family of 17 particles - well known ones such as the electron and the Higgs boson - as well as the lesser known but wonderfully named charm quark, tau neutrino and gluon.

From BBC

So, a particle that began as an electron neutrino might later appear as a tau neutrino—a phenomenon known as neutrino oscillation.

From Science Magazine

What it sacrifices in temporal resolution—it has none—it makes up for in spatial resolution, which will allow Feng and his colleagues to even identify the millimeter-long track from a tau neutrino decay.

From Scientific American

The particle is shown with a sharply defined mass state combination associated with an electron neutrino at its source and one indicating a tau neutrino at its destination.
