Final-state Phases in Doubly-cabibbo-suppressed Charmed Meson Nonleptonic Decays
نویسندگان
چکیده
Cabibbo-favored nonleptonic charmed particle decays exhibit large final-state phase differences in K̄π and K̄∗π but not K̄ρ channels. It is of interest to know the corresponding pattern of final-state phases in doubly-Cabibbosuppressed decays, governed by the c → dus̄ subprocess. An experimental program is outlined for determining such phases via measurements of rates for D → K∗π and K(ρ, ω, φ) channels, and determination of interference between bands in Dalitz plots. Such a program is feasible at planned highintensity sources of charmed particles.

U-Spin Symmetry in Doubly Cabibbo-Suppressed Charmed Meson Decays
We prove a U-spin amplitude triangle relation among doubly Cabibbosuppressed (DCS) charmed meson decays, D → Kπ, D → Kπ and D s → KK, congruent to an isospin relation among corresponding Cabibbo-favored (CF) decays. U-spin breaking in relative phases between CF and DCS amplitudes affects time-dependent studies of D −D0 mixing. Comparison of final state phase patterns in DCS and CF amplitude tri...
متن کاملTwo-body Cabibbo-suppressed decays of charmed baryons into vector mesons and into photons.
The heavy quark effective theory and the factorization approximation are used to treat the Cabibbo-suppressed decays of charmed baryons to vector mesons, ΛC → pρ, pω, Ξ C → Σφ,Σρ,Σω and Ξ0C → Λφ,Λρ,Λω. The input from two recent experimental results on ΛC decays allows the estimation of the branching ratios for these modes, which turn out to be between 10 and 10. The long distance contribution o...
متن کاملHadronic D Decays Involving Scalar Mesons
The nonleptonic weak decays of charmed mesons into a scalar meson and a pseudoscalar meson are studied. The scalar mesons under consideration are σ [or f0(600)], κ, f0(980), a0(980) and K 0 (1430). A consistent picture provided by the data suggests that the light scalars below or near 1 GeV form an SU(3) flavor nonet and are predominately the q2q̄2 states, while the scalar mesons above 1 GeV can...
متن کاملB/b̄ Flavour Tagging and Doubly Charmed B Decays in Aleph
This contribution concerns three contributed papers that share the common feature of analysing fully(or almost fully-) reconstructed B decays coming from a sample of four million hadronic Z decays collected with the ALEPH detector at LEP. In the first paper 1, 404 charged and neutral B mesons decaying in standard modes are fully reconstructed and used to look for resonant structure in the Bπ± s...
متن کاملFlavor Symmetry and Decays of Charmed Mesons to Pairs of Light Pseudoscalars
The application of SU(3) flavor symmetry to charmed particle decays can shed light on such questions as the strong phases of amplitudes in these decays. Such strong phases are non-negligible even in B decays to pairs of pseudoscalar mesons (P ), and can be even more important in D → PP decays. In the present paper we shall extract strong phases from charmed particle decays using SU(3) flavor sy...
