The beam consists of mostly muon neutrinos of energy around 2.5 GeV and expects a total exposure of 1.47 x [10.sup.21] POT running 3.5 years in neutrino mode and 3.5 years in
antineutrino mode.
The Daya Bay result provides the most precise measure yet of the energies of electron
antineutrinos at a nuclear reactor.
"The result is very exciting, because it essentially allows us to compare neutrino and
antineutrino oscillations in the future and see how different they are and hopefully have an answer to the question, Why do we exist?" Kam-Biu Luk, co-spokesperson of the experiment from the University of California, Berkeley, said.
Frederick Reines, who with Cowan had first detected the
antineutrino, now tried to detect neutrinos from the Sun.
Such oppositely moving neutrinos would make uncertain the choice of the charge sign in the next star, being admixed to the proper
antineutrinos generated by the positrons.
Antineutrinos are produced not only in the decay of uranium, thorium, and potassium isotopes but in a variety of others, including fission products in nuclear power reactors.
1919), set up the necessary detection system and snared a few
antineutrinos.
In the l - [[bar.[nu]].sub.l] center-of-mass frame, the four momenta of lepton and
antineutrino pair are given as
Each second, more than 10 scptillion ([10.sup.25])
antineutrinos race away from Earth and into space.
