초록

We present a measurement of the semileptonic mixing asymmetry for B-0 mesons, a(sl)(d), using two independent decay channels: B-0 -> mu+D-X, with D- ->! K+ pi(-) pi(-); and B-0 -> mu+D*X-, with D*(-) -> (D) over bar (0) pi(-), (D) over bar (-)(0) K+ pi(-) (and charge conjugate processes). We use a data sample corresponding to 10.4 fb(-1) of p (p) over bar collisions at root s = 1.96 TeV, collected with the D0 experiment at the Fermilab Tevatron collider. We extract the charge asymmetries in these two channels as a function of the visible proper decay length of the B-0 meson, correct for detector-related asymmetries using data-driven methods, and account for dilution from charge-symmetric processes using Monte Carlo simulation. The final measurement combines four signal visible proper decay length regions for each channel, yielding a(sl)(d) = [0.68 +/- 0: 45(stat) +/- 0.14(syst)]%. This is the single most precise measurement of this parameter, with uncertainties smaller than the current world average of B factory measurements.
