Description

A search with the large solid angle spectrometer (ARES) for the lepton-number-nonconserving decay μ+ → e+e+e- has been carried out. Cylindrical multiwire proportional chambers and cylindrical scintillation hodoscopes were used. The upper limit for the branching ratio Γ(μ+ → e+e+e-)/ Γ(μ+ → e+νeνμ) ≤ 3.6 x 10-11 (90% C.L.) has been derived. The investigation has been performed in the Laboratory of Nuclear Problems, JINR.
