Abstract

Using the ARGUS detector at the e+e- storage ring DORIS II at DESY, we have searched for decays b → sgluon through full reconstruction of a whole event. Two BB decays were found with one of B meson decaying into a final state without charmed particles. We also obtained an upper limit of Br(B+ → τ+ντ) of 1.04% at 90% CL.
