CLNS 02/1792 CLEO 02-10 Dalitz Analysis of D 0 → K 0 Sπ + π −

چکیده
In ee collisions using the CLEO detector we have studied the decay of the D to the final state K Sπ π with the initial flavor of the D tagged in charged D decay. We use the Dalitz technique to measure the resonant substructure in this final state and clearly observe ten different contributions by fitting for their amplitudes and relative phases. We observe a Kπ component which arises from doubly Cabibbo suppressed decays or D −D0

– 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...

We have searched for the charmless hadronic decay of B mesons into two neutral pions. Using 9.13 fb taken at the Υ(4S) with the CLEO detector, we obtain an improved upper limit for the branching fraction B(B → ππ) < 5.7 × 10 at the 90% confidence level.
متن کامل– 1 – Review of D - Meson Dalitz Plot Analyses
The formalism of Dalitz-plot analysis is reviewed in the preceding note. Recent studies of multi-body decays of charm mesons probe a variety of physics, including γ/φ 3 , D 0 –D 0 mixing, searches for CP violation, doubly Cabibbo-suppressed decays, and properties of S-wave ππ, Kπ, and K ¯ K resonances. In the following, we discuss: (1) D 0 → K 0 S π + π − ; (2) doubly Cabibbo-suppressed decays;...
متن کاملRecent Charm Results from Cleo
We describe two recent results using data collected with the CLEO detector at the CESR e + e − collider at energies near the Υ(4S). The first is a Dalitz plot analysis of the decay D 0 → K 0 S π + π −. We observe a rich structure including the decay D 0 → K * + π − which may be produced by D 0 − D 0 mixing or doubly Cabibbo-suppressed decays. We also search for D 0 − D 0 mixing in the decay D 0...

Determinations of the Cabibbo-KobayashiMaskawa matrix elements provide important checks on the consistency of the standard model and ways to search for new physics. The possibility of observing direct CP violation in B → DK decays was first discussed by I. Bigi, A. Carter and A. Sanda [1]. Since then, various methods to measure the weak angle φ3 (also known as γ) using B → DK decays have been p...
