We present a measurement of the mass difference Delta m(d) of the two B-d(0) 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 90 pb(-1) collected by the Collider Detector at Fermilab. The result obtained is Delta m(d)=0.503+/-0.064(stat)+/-0.071(syst) ps(-1).

Abstract
We present a measurement of the mass difference Delta m(d) of the two B-d(0) 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 90 pb(-1) collected by the Collider Detector at Fermilab. The result obtained is Delta m(d)=0.503+/-0.064(stat)+/-0.071(syst) ps(-1).
