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 …

Untersuchung zur Rekonstruktion von D*+- -Mesonen in Photoproduktion am H1-Detektor bei HERA
… charmed particles, especially charged excited D-mesons, are produced via the process of boson gluon fusion, their decay particles being detected in the H1 detector. In this thesis the cross section for the production of these charmed mesons is determined, which leads to a better understanding of …

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 …
