# Search for Decays of $B^0$ mesons into pairs of leptons

Abstract : We present a search for the decays B0->e+e-, B0->mu+mu-, and B0->emu in data collected at the Upsilon(4S) with the BABAR detector at the SLAC B Factory. Using a data set of 54.4 fb-1, we find no evidence for a signal and set the following preliminary upper limits at the 90% confidence level: B(B0->e+e-)< 3.3*10E-7, B(B0->mu+mu-) < 2.0*10E-7, and B(B0->emu) < 2.1*10E-7.
