Quantum Chromodynamics and Particle Interactions

Experimental results on the production of dimuons by 800-GeV protons incident on a copper target are presented. The results include measurements of both the continuum of dimuons and the dimuon decays of the three lowest-mass ϒ S states. A description of the apparatus, data acquisition, and analysis techniques is included. A comparison of the results with data taken at lower incident energies indicates a scaling behavior of the continuum dimuon yields.Received 29 October 1990DOI:https://doi.org/10.1103/PhysRevD.43.2815©1991 American Physical Society
