 Search for charmless decays of B mesons with the DELPHI detector
 (1997)
 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 $b\rightarrow s\gamma$ decays were found to be less than $5.1\times{10^{-4}}$. Dileptonic $b\rightarrow sl^+l^-$ decays in exclusive channels were also studied and we found upper limits in the order of 10$^{-3}$.
