Book Description
We present results of a search for D[sup 0]-[bar D][sup 0] mixing and a measurement of R[sub D], the ratio of doubly Cabibbo-suppressed decays to Cabibbo-favored decays, based on an analysis of D[sup 0][yields] K[sup+][pi][sup -] decays in 57.1 fb[sup -1] of data collected at or just below the[Upsilon](4S) resonance with the BABAR detector at the PEP-II collider. Our results are compatible with no mixing and no CP violation. At the 95% confidence level, allowing for CP violation, we find the mixing parameters x[prime][sup 2]

Book Description
Analyzing D{sup 0} {yields} K{sup +}{pi}{sup -}{pi}{sup 0} decays, herein are presented the methods and results of a search for D{sup 0}-{bar D}{sup 0} mixing, a measurement of the branching ratio R {equivalent_to} {Lambda}(D{sup 0} {yields} K{sup +}{pi}{sup -}{pi}{sup 0})/{Lambda}(D{sup 0} {yields} K{sup -}{pi}{sup +}{pi}{sup 0}), and measurements of the contributions from D{sup 0} {yields} K{sup +}{rho}{sup -}, K*{sup +}{pi}{sup -}, K*{sup 0}{pi}{sup 0}; 230.4 fb{sup -1} of data collected from the BABAR detector at the PEP-II collider during 2000-2004 (Runs 1-4) are analyzed. An event-level tagging technique is developed, which facilitates the accurate determination of doubly Cabibbo-suppressed resonance contributions by suppressing background from Cabibbo-favored decays. The branching ratio is measured as R = (0.214 {+-} 0.008 (stat) {+-} 0.008 (syst))%, with (46.1 {+-} 3.3 (stat) {+-} 2.9 (syst))% of D{sup 0} {yields} K{sup +}{pi}{sup -}{pi}{sup 0} decays proceeding through the channel D{sup 0} {yields} K*{sup +}{pi}{sup -}. The data are consistent with the null-D-mixing hypothesis at a confidence level of 10%, and the expected value of {+-} {radical}(x{sup 2} + y{sup 2}) is measured as -0.013 {+-} 0.010 (stat), indicating negative interference between mixing and doubly Cabibbo-suppressed decay. The expected value of the integrated mixing rate is (x{sup 2} + y{sup 2})/2 = (0.013 {+-} 0.013 (stat))%.

Book Description
We present a preliminary search for D°-{bar D}° mixing using the decays D° → K?−?°, additionally presenting Dalitz-plot distributions and a measurement of the branching ratio for this mode. A new tagging technique is used to produce the doubly Cabibbo-suppressed Dalitz plot, which in turn is used to motivate the method used for the D-mixing search. We analyze 230.4 fb−1 of data collected from the BABAR detector at the PEP-II collider. Assuming CP conservation, we find R{sub M}

Book Description
The authors present a search for D°-{bar D}° mixing using regions of phase space in which the rate of doubly Cabibbo-suppressed decays D° → K+?−?° relative to Cabibbo-favored decays D° → K− ?+?° is reduced. They analyze 230.4 fb−1 of data collected with the BABAR detector at the PEP-II e+e− collider at SLAC. They present results with and without the assumption of CP conservation. Assuming CP conservation, they measure the time-integrated mixing rate R{sub M} = (0.023{sub -0.014}{sup +0.018}(stat.) ± 0.004(syst.))%, and R{sub M}

Book Description
We presented the first observation of D0-$\bar{D}$0 mixing in a single analysis. We measured the ratio of doubly Cabibbo suppressed or WS (D0 → K+[pi]-) decay rate to Cabibbo favored or RS (D0 → K-[pi]+) decay rate as a function of D0 decay time. We used an integrated luminosity of 4.0 fb-1 of proton anti-proton collisions at √s = 1.96 TeV at the collider detector at Fermilab (CDF II).

Book Description
The D[sup 0] meson can decay to the wrong sign K[sup+][pi][sup -] state either through a doubly Cabibbo suppressed decay or via mixing to the[bar D][sup 0] state followed by the Cabibbo favoured decay[bar D][sup 0][yields] K[sup+][pi][sup -]. We measure the rate of wrong sign decays relative to the Cabibbo favoured decay to (0.383[+-] 0.044[+-] 0.022)% and give our sensitivity to a mixing signal.
