We present the results of a search for the radiative decay B0→J/ψγ in a data set containing 123.0×106 Υ(4S)→BB̅ 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

Abstract
We present the results of a search for the radiative decay B0→J/ψγ in a data set containing 123.0×106 Υ(4S)→BB̅ 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 levelFile in questo prodotto:
