Abstract

We present the results of a search for the radiative decay B0 → J/Ψγin a data set containing 123:0 × 106 Υ(4S) → BB̄ decays, collected by the BABAR detector at the PEP-II asymmetric-energy e+e- storage ring at SLAC.We find no evidence for a signal and place an upper limit of B(B0 → J/Ψγ) < 1:6 × 10-6 at 90% confidence level.
