Production of Intermediate Bosons in Strong Interactions

From data on muon pairs and by use of the hypotheses of conservation of vector current and scale invariance, we estimate the cross section for production of weak vector mesons W^± at energies pertinent to Brookhaven National Laboratory, the CERN intersecting storage rings, and the National Accelerator Laboratory. With existing data, these estimates imply a lower limit of 4.5 GeV/c² for the W^± mass.
