Dimuon production cross sections were measured with a 200 GeV ..pi../sup -/ beam and a 240 GeV proton (p) beam. The dimuon mass spectra produced by ..pi.. and p have essentially the same shape. The dimuon transverse momentum behavior is essentially the same for vector mesons produced by ..pi.. or by p. For (rho + ..omega..) or psi production the x (Feynman) behavior is approximately independent of the mass of the dimuon produced. The dimuon ..pi.. production cross section is approximately 6 times greater than that of the p for x greater than .5. Using a missing mass (M/sub m/) technique, the same pion and proton beams were used to search for the production in hydrogen of new particles which decay with muon emission. Model dependent upper limits (50 to 7000 nanobarns) for the production of such objects with 2.5 less than M/sub m/ less than 7. GeV are given (for charmed meson pair production M/sub m/ is the mass of the D anti D system).
