Charmonium and Charmed Mesons With Improved Lattice QCD
… calculations of the properties of charmonium and charmed mesons with lattice QCD. The calculations use improved actions and 2+1 flavors of dynamical quarks. After a review of the relevant phenomenology, I provide an introduction to lattice techniques including the specific actions used in this …

Search for semileptonic decays of photoproduced charmed mesons
… at Fermi1ab, a search for photoproduction of charmed D mesons has been done using photons of 100 to 300 GeV. The reaction considered was [equation] s No statistically significant evidence for D production is observed based on the Ksnpi± mass spectrum. The sensitivity of the search is …

Mixing and Doubly Cabibbo -Suppressed Decays of Neutral Charmed Mesons
"A study of the decay D0 → K+pi-pi+pi - is presented. This ""wrong-sign"" decay can proceed through either a doubly Cabibbo-suppressed decay or mixing to a D¯0 followed by the Cabibbo-favored (or ""right-sign"") decay D0 → K-pi+pi-pi +. The Cabibbo-favored decay is used as a …

Resolution Studies for the Micro Vertex Detector of the PANDA Experiment and the Reconstruction of Charmed Mesons for Specific Hadronic Channels
… can 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 …

First measurement of the gluon polarisation in the nucleon using D mesons at COMPASS
… pair and <br>is then tagged by detecting the charmed mesons in the final state. <br>This approach is used in this thesis and results in a theoretically very clean sample of PGF events, assuming that the intrinsic charm content in the nucleon is negligible. <br>Since the charm tagging of the …

Production of charm mesons by high energy neutrons
"The charmed mesons D""'±, DO, and D; have been observed in neutron-nucleus collisions at the FNAL Tevatron. A sample of 134 ± 19 events was investigated in the decay D""'±-+ D°1r± with the subsequent decay mode D°-+ K+ K-. The cross section per nucleon for D""'±, at most probable energy ...;s = 35 …

Heavy quark symmetry in the soft collinear effective theory
… interaction effects in nonleptonic decays of ... mesons with energetic particles in the final state. An introduction to Soft Collinear Effective Theory (SCET), the appropriate effective field theory of QCD for such decays, is given. We focus on decays of the type ... where M is a light energetic …

Open and Hidden Charm Mesons at Finite Temperature from Anisotropic Lattice QCD
… study the dissociation of open and hidden charm mesons. Lattice QCD provides a non-perturbative means of studying the spectral quantities of charmed mesons. The suppression of J= in medium is widely considered to be a signal for deconfinement. I will use J= to study the heavy quark diffusion …
