Abstract

We report a measurement of the charge asymmetry for same-sign dileptons in B0-B̄0 mixing, Asl. The data were collected with the Belle detector at KEKB. Using a data sample of 78fb-1 recorded at the Υ(4S) resonance and 9fb-1 recorded at an energy 60 MeV below the resonance, we measure Asl=(-1.1±7.9(stat)±8.5(sys))×10-3.
