Measurement of the B[sub d][sup 0][bar B][sub d][sup 0] oscillation frequency using dimuon data in p[bar p] collisions at [radical] (s) =1. 8 TeV

We present a measurement of the mass difference [Delta]m[sub d] of the two B[sub d][sup 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[sup [mi...

Description
Summary:We present a measurement of the mass difference [Delta]m[sub d] of the two B[sub d][sup 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[sup [minus]1] collected by the Collider Detector at Fermilab. The result obtained is [Delta]m[sub d]=0.503[plus minus]0.064(stat)[plus minus]0.071(syst) ps[sup [minus]1]. thinsp [copyright] [ital 1999] [ital The American Physical Society]
