Dr. Melvin Schwartz Awarded Nobel Prize for Discovery of the Muon-Neutrino (1988). Neutrino Physics & Experiment 1. Past History Neutrino physics has had an interesting history. In 1930 Dr. Pauli postulated the existence of the (electron) neutrino, in 1956 this was confirmed by Drs. Reines and Cowan using a nuclear reactor source of antineutrinos. In 1962, a second distinct (muon) neutrino was shown to exist in a BNL experiment. For that discovery Nobel Prize was awarded to Drs. Lederman, Schwartz and Steinberger . In 1995, the third, (tau) neutrino was detected at FNAL. In parallel, Dr. Ray Davis’ studies of solar neutrinos confirmed understanding of stellar dynamics modulo a 2/3 flux deficit that later was recognized as a result of ν oscillations among the three flavors of neutrinos. Properties of those oscillations were further unveiled with followup solar, atmospheric, reactor and accelerator neutrino studies. The discovery of oscillations, detection of 19 neutrino events from supernova 1987a by the old IMB and Kamiokande water cherenkov detectors confirmed the theory of supernova explosions. The WMAP experiment has started to see imprints of neutrino mass effects on cosmic microwave back ground radiation left from the Big Bang. 2. Introduction In 1998 Dr. Zohreh Parsa started the Neutrino CP Violation studies, extra L ong B aseline (L, 2000 kmL4000 km) N eutrino (LBN) oscillation Physics and E xperiment (LBNE) that envisioned sending a very intense neutrino (ν) beam (e.g., from Brookhaven National Laboratory on Long Island, New York), through the earth to a far away underground multipurpose large detector capable of making precision measurements of all the (ν) neutrino oscillation parameters, Proton decay and observation of natural sources of neutrinos such as supernova, providing a major advances in neutrino science. The key to this approach is (extra long) very long distance L. Length of the Baseline defines the physics you can do, once chosen, can not be changed without establishing a new facility. Extra Long Base lines provide possibility of observing multiple nodes of the Neutrino oscillation probability in appearance and disappearance experiments. By measuring muon neutrino disappearance and electron neutrino appearance, such a project would be capable of determining all 3 generation mixing angles, mass hierarchy, along with magnitude of the CP violation (e.g., by measuring CKM phase and explicitly observing differences in the muon neutrino and muon anti-neutrino oscillations). No existing experiment so far has such capability. E.g., Neutrinos emitted in the first few seconds of a core-collapse supernova, would have...
