چکیده
We present preliminary results from Fermilab E791 on D 0 ? D 0 mixing and doubly Cabibbo-suppressed decays (DCSD) of the D 0 and D + mesons. The time dependence of the wrong-sign signal (D 0 ! K + ?) is used to establish separate limits on DCSD and mixing. From one third of our data we obtained r mix < 0:47%, r DCSD < 2:7% at the 90% conndence level.

Measuring D 0 – D 0 Mixing and Relative Strong Phases at a Charm Factory 1
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 D...

متن کاملOf 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 KK resonances. In the following, we discuss: (1) D 0 → K 0 S π + π − ; (2) doubly Cabibbo-suppressed decays; and...
متن کاملCp Violation in Charm
Recent results on searches for CP and CPT violation in the charm sector are presented. These results include limits on direct CP violation in several channels from the FOCUS and CLEO experiments. The first reported search for CPT violation in charm, a preliminary result by the FOCUS collaboration, is also presented. 1 Charm CP Violation Introduction CP violation is generally divided into three ...
متن کاملPhenomenology of Neutral D − meson Decays and Double - Flavor Oscillations 1 Ya
Decays of neutral D-mesons are considered phenomenologically without invoking any particular models. Special attention is given to cascade decays with intermediate neutral kaons where coherent double-flavor oscillations (CDFO) become possible. We show necessity and unique possibilities of experiments on CDFO. They allow to relate with each other widths and masses of D-meson eigenstates, to sepa...
