Book Description
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 Description
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 Description
A report is given on studies on dimuon production in the high energy neutrino and antineutrino induced events accrued during an experiment to measure normalized neutrino and antineutrino cross sections at incident energies between 30 and 220 GeV. The rates, energy dependence, and scaling are discussed. (JFP).

Book Description
The editors are pleased to submit to the readers the state of the art in high energy physics as it appears at the beginning of 1978. Appreciation is extended to Mrs. Helga S. Billings for her assistance with the conference and for her skillful typing of the proceedings which was done with great enthusiasm and dedication. Also, appreciation is extended to Dr. Osman Kadiro~u for his assistance with the proceedings this year. Orbis Scientiae 1978 received some support from the Department of Energy.
