Abstract

Using the ARGUS detector at the DORIS II e + e - storage ring, we have searched for gluinos ( g ), the supersymmetric partner of the gluon, by looking for secondary decay vertices in hadronic decays of χ b (1 3 P 1 ) mesons. Events containing χ b (1 3 P 1 ) states were selected by detecting the radiative transition from the ϒ (2S) in a data set corresponding to an integrated luminosity of 38.6 pb −1 . The absence of secondary vertices from gluino decays into hadrons and a photino allows us to exclude gluinos in a mass range from 1 to 4.5 GeV/c 2 and a lifetime range from 10 −11 to 10 −9 s.
