We have measured inclusive muon production in e + e − annihilation for CMS energies between 3.6 and 5.0 GeV. Above 4 GeV the cross section cannot be explained by conventional sources like higher order QED processes or inclusive production of the J ϑ (3.1). It is, however, compatible with the pair production of heavy particles of a mass of about 1.9 GeV/ c 2 . Spin assignment and decay parameters are investigated.
