Search for new short-lived particles in collisions between 60 GeV/cπ- mesons and emulsion nuclei
We investigated the vicinities of —10000 stars from interactions of π- mesons with emulsion nuclei at a momentum 60 GeV/c. We found one event that can be interpreted as a leptonic decay of a new particle. Under resonable assumptions concerning the decay mode, the effective mass of the particle is — 2.4 GeV and its lifetime is ~ 10"14 sec.
