Search for CP violation in D-meson decays
Using data from the Mark III detector at the $e\sp+e\sp-$ storage ring at SPEAR, an upper limit of.30 at the 90% confidence level is set on the magnitude of the CP asymmetry $A\sb{cp}$ for the CP eigenstate $D\sp0\to K\sp+K\sp-.$ This falls within the preexisting limit of.45 @ 90% CL set by FNAL …

Search for CP violation in D-meson decays
Using data from the Mark III detector at the e+e- storage ring at SPEAR, an upper limit of .30 at the 90% confidence level is set on the magnitude of the CP asymmetry Acp for the CP eigenstate no -+ K+ K-. This falls within the preexisting limit of .45 @90% CL set by FNAL experiment E691 using the …

Non-D meson anti D meson decays of the Psi'' meson(3770)
A search for inclusive non-DD decays of the $\Psi\sp{\prime\prime}$(3770) is performed in a sample of 9.56 $\pm$ 0.48 pb$\sp{-1}$ collected by the Mark III detector at the SPEAR storage ring, at the Stanford Linear Accelerator Center. To be more specific, a search for inclusive p, $\bar \Lambda$, …

A Measurement of the Branching Fraction B(positive Strange D Meson Decays to Meson Positive Pion) at CLEO
I present a model-independent measurement of the ratio of branching fractions BD+s→ fp+ /BD0→K +p- by partially reconstructing the decay B0→D*+s D*- . Using 8.9fb-1 of on-resonance data collected with the CLEO II detector at CESR and the known value of BD0→K +p- , I determine …

Resolution Studies for the Micro Vertex Detector of the PANDA Experiment and the Reconstruction of Charmed Mesons for Specific Hadronic Channels
… contribute to understand the binding of charmed mesonic systems. Charmonium states can decay to open-charm channels which provide a clear signature in the detector from the charged D-Meson decays. In this work the high selection ability of the experimental setup was investigated for two reaction …
