Production of Muon Pairs by 225-GeV pi+-, K+, p+- Beams on Nuclear Targets

Results are presented from a large-acceptance experiment in which muon-pair production was observed in the mass range 2 to 11 GeV/c/sup 2/. Data were taken with ..pi../sup + -/, K/sup +/, and p/sup + -/ beams at 225 GeV/c on carbon, copper, and tungsten targets. Differential cross sections and the production dependence on pair mass, x/sub F/, p/sub T/, incident-particle type, and target nucleus are discussed.
