Book New Results on Dimuon Production by High Energy Neutrinos and Antineutrinos Rates GIM Model

Download or read book New Results on Dimuon Production by High Energy Neutrinos and Antineutrinos Rates GIM Model written by and published by . This book was released on 1978 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The rates for neutrino induced .mu.−.mu., .mu.−.mu.−, and .mu.−.mu.−.mu.+ events all relative to the charge-current interaction rate are presented. It is shown that the data suggest that a .nu.-induced prompt .mu.−.mu.− signal may in fact exist. But no clear evidence has as yet been established for prompt .mu.−.mu.− events from anti .nu. interactions. It is shown that both the rates and properties of the opposite-sign dimuon events are consistent with the GIM model. Based on this model these data may be used to determine f/sub s/, the amount of strange quark relative to valence d-quark in the nucleon. The data give approximately f/sub s/ approximately tan2theta/sub c/ = 0.05. 13 references. (JFP).

Book Dimuon Production by High Energy Neutrinos and Antineutrinos in the Fermilab Fifteen foot Bubble Chamber 60 and 89 GeV

Download or read book Dimuon Production by High Energy Neutrinos and Antineutrinos in the Fermilab Fifteen foot Bubble Chamber 60 and 89 GeV written by and published by . This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fermilab fifteen-foot bubble chamber/two-plane External Muon Identifier (EMI) hybrid detector filled with Ne(47% atomic)-H2 is exposed to the quadrupole triplet beam ( = 89 GeV, = 60 GeV). In 326,000 pictures there are 10,148 neutrino and 1773 antineutrino charged current events with two-plane EMI muon identification and muon momenta> 4 GeV/c. In this sample there are 55 .mu.−.mu. X, 11 .mu.−.mu.−X and 0 .mu.mu.+X candidates with muon momenta> 4 GeV/c. The like-sign events are consistent with background. The opposite-sign dimuons occur at R/sub .mu. .mu./ = 0.35 +- 0.10% of the single muon rate. The .nu./sub .mu./-induced .mu.−.mu./sup +/ rate is 0.20 +- 0.15% below E/sub nu//sub .mu./ = 100 GeV and 0.50 +- 0.30% above 100 GeV. In the opposite-sign dimuons there are 10 candidates with an associated V° implying 0.76 +- 0.36 neutral strange particle per opposite-sign dimuon event. The production rate, excess of neutral strange particles, and kinematic distributions of the dimuon events are consistent with the charm model predictions. 56 references.

Book Measurement of Same sign Dimuon Production in High energy Neutrino Interactions

Download or read book Measurement of Same sign Dimuon Production in High energy Neutrino Interactions written by and published by . This book was released on 1987 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present rates for same-sign dimuon production in neutrino-iron interactions with energies of 30 to 600 GeV. We find 101 neutrino and 15 anti-neutrino induced same-sign dimuons with muon momenta above 9 GeV/c. A detailed calculation indicates that the overall level and kinematic distributions of conventional backgrounds are consistent with the data. There is no convincing indication of new physical processes. 16 refs., 11 figs., 1 tab.

Book Physics and Astrophysics of Neutrinos

Download or read book Physics and Astrophysics of Neutrinos written by Masataka Fukugita and published by Springer Science & Business Media. This book was released on 2013-12-14 with total page 947 pages. Available in PDF, EPUB and Kindle. Book excerpt: Observations of neutrinos being emitted by the supernova SN1987A, star neutrinos, and atmospheric neutrinos have provided new insights into astronomy, as well as new unresolved phenomena such as the solar neutrino problem, spurring investigative studies among particle physicists and astrophysicists. One of the most important features of this book is its enumeration of a number of basic properties of neutrinos and their relationship to Grand Unified Theories, focusing on the origin of the neutrino's mass and the generation mixing of neutrinos. All the kamiokande results, detector performances, and complete references are included.
