unlike originally assumed in the standard model of particle physics. Neutrino oscillation experiments have shown that the weakly interacting neutrino flavour eigenstatesνf, wheref ∈ {e, μ, τ} for electron, muon and tau-neutrino, are admixtures of the three neutrino-mass eigenstatesν...

A beam of 5-MeV neutrinos would be reduced in intensity by 50% in traveling through 45 light years of water! Reaction (5) is used for detecting neutrinos from the sun. It is the inverse of the electron capture of 37Ar [see reaction (3)], a decay process with a half-life of 35 ...
anda beta particle. Because only the electron and the recoiling daughter nucleus were observed beta decay, the process was initiallyassumed to be a two-body process, very much like alpha decay. It would seem reasonable to suppose that the beta particles would also form amonoenergeti...
The neutrino was first postulated in 1931 by Wolfgang Pauli to explain the energy spectrum of beta decays, the decay of a neutron into a proton and an electron. Pauli theorized that an undetected particle was carrying away the observed difference between the energy and angular momentum of the ...

These detectors can also be placed sparsely in an array extended beyond the main detector volume, to detect cosmogenic neutrinos with energies well above exaelectronvolts44,...
