An analysis of multihadronic events produced with two energetic leptons in e +e − annihilation

A search for multihadronic events produced with two energetic leptons has been performed at PETRA using 130 pb −1 accumulated by the CELLO detector at 35 GeV ⩽ √ s ⩽46.8 GeV. Three μ + μ −, eleven e +e − and three eμ events were observed. The mesured yields an dthe event characteristics are in good...

Zusammenfassung:A search for multihadronic events produced with two energetic leptons has been performed at PETRA using 130 pb −1 accumulated by the CELLO detector at 35 GeV ⩽ √ s ⩽46.8 GeV. Three μ + μ −, eleven e +e − and three eμ events were observed. The mesured yields an dthe event characteristics are in good agreement with the expectation for the α 4 QED processes e + e − → ℓ +ℓ − q q and from semileptonic decays of pairs of heavy quarks.
