I've noticed the strangest thing about men who hang out in bars a lot.
It seems they have only one of two reasons to be there.
They have no wife to go home to... or they do!
Tau neutrinoIn 2000, an international collaboration of scientists at the Department of Energy's Fermi National Accelerator Laboratory announced the first direct evidence for the subatomic particle called the tau neutrino, the third kind of neutrino known to particle physicists. They reported four instances of a neutrino interacting with an atomic nucleus to produce a charged particle called a tau lepton, the signature of a tau neutrino. The tau (rhymes with "now") neutrino is the third neutrino of the Standard Model of elementary particles, a theoretical description that groups all particles into three generations. Experimenters identify them by recording neutrino interactions. First generation electron neutrinos were created in 1956, and second generation muon neutrinos in 1962. |
