Abstract

The Β⁰-̄Β⁰ mixing parameter Δm_d was measured using Β⁰→D^*-ℓ⁺ν decays in a 29.1 fb^-1 data sample collected with the Belle detector at the KEKB e⁺e^- collider operating at the Υ(4s) resonance. From an unbinned maximum-likelihood fit to the Δt distribution for Β pairs with the same and opposite flavors, it was possible to obtain Δm_d=0.494±0.012(stat)±0.015(syst) ps^-1.
