# Search for decays of $B^0 \to e^+ e ^-, B^0 \to \mu^+ \mu^-, B^0 \to e^{pm} \mu{mp}$

Abstract : We present a search for the decays B0-->e+e-, B0-->µ+µ-, and B0-->e±µ-/+ in data collected at the Upsilon(4S) resonance with the BABAR detector at the SLAC B Factory. Using a data set of 111 fb-1, we find no evidence for a signal in any of the three channels investigated and set the following branching fraction upper limits at the 90% confidence level: [script B](B0-->e+e-)<6.1×10-8, [script B](B0-->µ+µ-)<8.3×10-8, and [script B](B0-->e±µ-/+)<18×10-8.
