Nonleptonic weak decays of charmed mesons.
A previous analysis of two-body Cabibbo allowed nonleptonic decays of D mesons and of Cabibbo allowed and first-forbidden decays of D and D s has been adjourned using more recent experimental data and extended to the Cabibbo forbidden decays of D. Annihilation and W-exchange contributions as well as final state interaction effects (assumed to be dominated by nearby resonances) have been include...
متن کاملCabibbo-allowed nonleptonic weak decays of charmed baryons.
Cabibbo-allowed nonleptonic weak decays of charmed baryons Λ + c , Ξ 0A c , Ξ +A c and Ω 0 c into an octet baryon and a pseudoscalar meson are analyzed. The nonfactorizable contributions are evaluated under pole approximation, and it turns out that the s-wave amplitudes are dominated by the low-lying 2 − resonances, while pwave ones governed by the ground-state 2 + poles. The MIT bag model is e...
متن کاملFinal-state Phases in Doubly-cabibbo-suppressed Charmed Meson Nonleptonic Decays
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) cha...
متن کاملMeasurements of Cabibbo-suppressed hadronic decays of charmed D+ and D0 mesons.
Measurements of the branching ratios of ten Cabibbo suppressed hadronic weak decays of the II+ and Do are presented from data collected with the Mark III detector at SPEAR. In addition to the previously observed channels Do-) K-K+ and T-T+, we report new measurements of Do + r-rr+~O and ?r-n+rr-7rlr+; We present measurements of Cabibbo suppressed hadronic weak decays of the D+ and Do into two, ...
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...
