We present a study of time dependent B⁰-$$\bar{B}$$⁰ mixing in p$$\bar{p}$$ collisions at 1.8 TeV using 110 pb^-1 collected with the CDF detector at the Fermilab Tevatron Collider. B mesons are partially reconstructed using the semileptonic decays B⁰→l⁺D^*-X and B⁺→l⁺$$\bar{D}$$⁰X (and their charge conjugates). B meson-charged pion correlations are used in order to determine the flavor of the B meson at t=0. Such correlations are expected to arise from pions produced in the fragmentation chain and also from B** decays. We measure the efficiency and purity of this flavor tagging method for both charged and neutral B mesons.
