摘要We investigate the D-0-(D) over bar (0) mixing through the doubly Cabibbo suppressed (DCS) channel D-0 -> f(0)(980)K*(0) and its charge conjugate channel, in which the K*(0) meson is reconstructed in both K+pi(-) and K-S pi(0) final state. Although the decay D-0 -> f(0)(980)K* has a small branching ratio, the final state mesons are relatively easy to identify. The f(0)(980) meson can be replaced by the S-wave pi(+)pi(-) state, or a longitudinally polarized vector meson rho(0). All mixing parameters, including the mass difference and decay width difference, can be extracted by studying the time-dependent decay width of these channels. We show that the method is valid in all regions for mixing parameters and it does not depend on the strong phase difference.
