Neutrino Physics
Neutrino oscillations arise from a quantum mechanical phenomenon associated with the fact that the neutrinos have mass. For the three neutrinos species that we know to exist, the principle of superposition allows "flavor" states, namely neutrinos that interact to produce electrons, muons, or taus, to be (orthogonal) combinations of three neutrino states with definite mass.

Tracking Down the Origin of Neutrino Mass. Collider experiments have set new direct limits on the existence of hypothetical heavy neutrinos, helping to constrain how ordinary neutrinos get their mass. Figure 1: In the seesaw mechanism, a hypothetical neutrino (left) is "mixed" with an observed neutrino (right).

The hypothesis of the neutrino allowed Fermi to build the first theory of the β-decay which he considered as a process of a quantum transition of a neutron into a proton with the creation of an electron-(anti)neutrino pair. During many years this was the only experi-mentally studied process in which the neutrino ...

A Review of Neutrino Physics
Neutrino physics is built upon a number of theoretical underpinnings. With decades of hindsight we can build up the necessary quentum field theories systematically and unify them in a manner that obeys mathematical restrictions motivated by physical observations. From those theories we can model complex interactions and understand one of the ...

The Early Days of Experimental Neutrino Physics
Abstract. The neutrino hypothesis, put forward by Pauli to account for the apparent loss of energy and momentum in beta decay, was verified by a series of measurements at a nuclear reactor nearly 25 years ago. An account is given of the first observations of the interaction of neutrinos in a target remote from the fission process that produced ...

Neutrino
A neutrino (/ nj uː ˈ t r iː n oʊ / new-TREE-noh; denoted by the Greek letter ν) is a fermion (an elementary particle with spin of 1 / 2) that interacts only via the weak interaction and gravity. The neutrino is so named because it is electrically neutral and because its rest mass is so small that it was long thought to be zero.The rest mass of the neutrino is much smaller than that of ...
