Abstract

We describe a measurement of B - B̄ mixing parameters exploiting a method of partial reconstruction of the decay chains B̄ → D(* ±)π(±) and B̄ → D(* ±) ρ (±). Using 9.6 x 10 BB̄ pairs collected at the Cornell Electron Storage Ring, we find χ(d) = 0.198 ± 0.013 ± 0.014, |y(d)| < 0.40 at 95% confidence level, and |(R) e(ε(B)| < 0.034 at 95% confidence level.
