Abstract

Evidence for charmless b decay are observed in two body hadronic modes in a data sample of three million hadronic Z 0 decays collected with the DELPHI detector at the LEP collider from 1991 to 1994. No signal is observed in any of the investigated three or four bodies channels. Radiative b → sγ decays were found to be less than 5.1 × 10 −4. Dileptonic b → sl + l − decays in exclusive channels were also studied and we found upper limits in the order of 10 −3.
