– 1 – Review of Charm Dalitz Plot Analyses

The formalism of Dalitz-Plot analysis is reviewed in the preceeding note. Table 1 lists reported analyses of D mesons. In the following, we discuss a number of subjects of current interest: (1) D0 → K0 Sππ; (2) D → πππ: a σ(500) or f0(600); (3) D+ → K−π+π+: a κ(800)? (4) the f0(980), f0(1370) and f0(1500); (5) doubly Cabibbo-suppressed decays; and (6) CP violation. D0 → K0 Sππ: Several experime...

2001 Measuring D 0 – D 0 Mixing and Relative Strong Phases

We propose a set of measurements at a charm factory to determine the D– D 0 mixing parameters ∆M and ∆Γ and the strong phase difference δ between doubly-Cabibbo-suppressed (DCS) and Cabibbo-favored (CF) neutral D decays into Kπ. The method can also be used to measure strong phase differences between other corresponding DCS and CF amplitudes. These phase differences are important for studies of ...

Hadronic Charm Decays in Cleo

We present several results on hadronic D meson decays. We report on results from the scan of the energy region from 3970 MeV to 4260 MeV, which was used to determine an optimal energy to carry out the Ds physics program of CLEO-c. Improved measurements of inclusive and exclusive D and Ds branching fractions are presented. We also show results on Dalitz analyses of D+ → π+π−π+ using CLEO-c data ...

Determination of the strong phase in D0-->K+pi- using quantum-correlated measurements.

We exploit the quantum coherence between pair-produced D0 and D[over]0 in psi(3770) decays to study charm mixing, which is characterized by the parameters x and y, and to make a first determination of the relative strong phase delta between D0-->K+pi- and D[over]0-->K+pi-. Using 281 pb(-1) of e+e- collision data collected with the CLEO-c detector at Ecm=3.77 GeV, as well as branching fraction i...

Search for D 0 −D 0 Mixing CLEO Collaboration

We report on a search for D0−D0 mixing made by a study of the ‘wrong-sign’ process D →K+π−. The data come from 9.0 fb of integrated luminosity of ee collisions at √ s ≈ 10GeV, produced by CESR and accumulated with the CLEO II.V detector. We measure the time-integrated rate of the ‘wrong-sign’ process D → Kπ, relative to that of the Cabibbo-favored process D0→K+π−, to be Rws = (0.34 ± 0.07 ± 0.0...
