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...
