We present a measurement of the mass difference Δmd of the two Bd0 mass eigenstates. We use a flavor tagging method based on the lepton charge, in a sample of events with two muons at low transverse momentum. The sample corresponds to an integrated luminosity of 90pb-1 collected by the Collider Detector at Fermilab. The result obtained is Δmd=0.503±0.064(stat)±0.071(syst)ps-1.
