The muon neutrino is an elementary particle which has the symbol ν μ and zero electric charge. Together with the muon it forms the second generation of leptons, hence the name muon neutrino. It was discovered in 1962 by Leon Lederman, Melvin Schwartz and Jack Steinberger. The discovery was rewarded with the 1988 Nobel Prize in Physics.
Below is the list of muon (anti)neutrino beams used in past or current physics experiments: CERN Neutrinos to Gran Sasso (CNGS) beam [10] produced by Super Proton Synchrotron at CERN used in OPERA and ICARUS experiments. Booster Neutrino Beam (BNB) produced by the Booster synchrotron at Fermilab used in SciBooNE, MiniBooNE and MicroBooNE ...
In the 1980s, monitored neutrino beams were built in the USSR in the framework of the "tagged neutrino beam facility". [7] This facility did not reach a flux sufficient to feed neutrino experiments and was later descoped to a tagged kaon beam facility. Current neutrino beams record muons but they have not reached single-particle sensitivity.
This beam then passed 732 kilometres (455 mi) through the crust of the Earth and it is expected that during flight some of the muon neutrinos convert into other neutrino types such as tau neutrinos. [1] Once the beam arrived at Gran Sasso, the OPERA and ICARUS experiments were used to detect the neutrinos.
T2K was the first experiment which observed the appearance of electron neutrinos in a muon neutrino beam. [5] It also provided the world best measurement of oscillation parameter θ 23 [6] and a hint of a significant matter-antimatter asymmetry in neutrino oscillations.
The researchers concluded that the one spotted at ARCA - which was a type of neutrino called a muon - was of cosmic origin based on its horizontal trajectory and the fact that it had traversed ...
The dominant muon decay mode (sometimes called the Michel decay after Louis Michel) is the simplest possible: the muon decays to an electron, an electron antineutrino, and a muon neutrino. Antimuons, in mirror fashion, most often decay to the corresponding antiparticles: a positron, an electron neutrino, and a muon antineutrino. In formulaic ...
The neutrino [a] was postulated first by Wolfgang Pauli in 1930 to explain how beta decay could conserve energy, momentum, and angular momentum ().In contrast to Niels Bohr, who proposed a statistical version of the conservation laws to explain the observed continuous energy spectra in beta decay, Pauli hypothesized an undetected particle that he called a "neutron", using the same -on ending ...
