The Berkeley-Fermilab-Princeton multimuon spectrometer and the techniques used to analyze the data which it has collected are described first. Limits on the cross section with which possible heavy neutral or doubly charged muons are produced via right-handed charged currents are presented. Turning to heavy-quark muoproduction, the author then outlines the relevant phenomenology, emphasizing the predictions of the vector dominance (VMD) and photon-gluon-fusion models. The first heavy-quark data discussed are the dimuon-mass spectrum observed in trimuon final states, which provides a limit on muoproduction of the UPSILON family. The bulk of the quarkonium results are devoted to J/psi(3100) muoproduction. After briefly reviewing the original psi results, the author focuses on a combined analysis of the polarization and Q/sup 2/ dependence of elastically produced psi's. The remainder of the paper is devoted to the muoproduction of open charm, observed in events with two muons in the final state. 57 references, 11 figures, 3 tables. (RWR)
