Description
In the SKAT bubble chamber neutrino experiment production of a short-living neutral particle with mass (1.4<=m<=2.5) GeV/c2 and lifetime tau approximately 6x10-12 s has been detected. The event may be interpreted as production and decay of the heavy lepton M0→μ-+e++γsub(e) with mass (1.4<=msub(M0)<=2.1) GeV/c2. It might also be the production of a charmed particle D0→e++tau-+γsub(e) (D0→K0+e++π-+γsub(e) with mass (1.4<=msub(D0)<=2.5) GeV/c2 in a nondiagonal neutral current. The probability to interpret the event as other possible processes is very low. (Auth.)
