| dc.description | With the BaBar detector at the PEP-II asymmetric $B$ Factory at SLAC, we present the first search for the decays $B^0\to\ell^+\ell^-γ$ ($l=e, μ$). Using a data set of 292 $fb^{-1}$ collected at the $Υ(4S)$ resonance, we find no significant signal and set the following branching fraction upper limits at 90% confidence level: $\mathcal{B}(B^0\to e^+e^-γ)<0.7\times 10^{-7}$ and $\mathcal{B}(B^0\to μ^+μ^-γ)<3.4\times 10^{-7}$. | |
