Abstract

We have observed events of the form e⁺+e^- → e⁺+e^- and e⁺+e^- → μ⁺+μ^- in which there are no other detected particles and there is substantial missing energy; and which cannot be explained by conventional electromagnetic interactions. We show that these events can be explained as the decay products from the pair production, e⁺+e^- → τ⁺+τ^-, of a new charged lepton, τ^±, of mass ≈1800 MeV/c². Some properties of these events are presented. In particular, this production cross section is inconsistent with the τ being an electron-related paralepton.
