A Strong QCD Enhancement of CP Violation in Charmed Meson Decays?
نویسندگان
چکیده
The mass difference of c and u quarks is similar to the energy needed to excite gluonic degrees of freedom in strong QCD. This underpins the degeneracy of D and a recently observed candidate hybrid excitation of the π at∼ 1.8GeV and may generate a strong analogue of Penguin mixing together with a measurable CP-violation in D and Ds decays.

Charming penguin and direct CP-violation in charmless B decays
In the study of two-body charmlessB decays as a mean of looking for direct CP-violation and measuring the CKM mixing parameters in the Standard Model, the short-distance penguin contribution with its absorptive part generated by charm quark loop seems capable of producing sufficient B → Kπ decays rates, as obtained in factorization and QCD-improved factorization models. However there are also l...
متن کاملCP violation in charm decays
Non-perturbative hadron dynamics plays an important role in the physics of non-leptonic D decay. The existence of the light quark resonances in the neighborhood of the charmed meson mass is a proof that hadron dynamics is active in this energy region and might a ect weak decays of charmed particles. Similar e ects, like nal state hadron rescattering, can completely obscure a naive quark model i...
متن کاملCharm Physics Results from CLEO The CLEO Collaboration
We present recent results in the charm sector from the CLEO Collaboration. The data used were collected by the CLEO II and III detectors at the Cornell Electron Storage Ring (CESR). Measurements of form factors and branching fractions in semileptonic decays of D-meson and charmed-baryons, searches for CP violation and rare decays, and Dalitz analyses of D-meson decays are discussed, as well as ...
متن کاملCharm Leptonic and Semileptonic Decays
The study of charmed meson decays are important for improving our knowledge of the Standard Model (SM). In particular, the study of leptonic and semileptonic decays allow us to measure the CKM matrix elements Vcs and Vcd to a high level of precision. Leptonic and semileptonic decays are also used to test theoretical predictions describing the strong interaction (QCD) in heavy quark systems. Cha...
متن کاملV decays in the perturbative QCD approach
Two-body non-leptonic charmed decays B(s) → D(s)P , D (s)P , D(s)V and D (s)V are analyzed in perturbative QCD approach, where P and V denote the light pseudoscalar meson and vector meson, respectively. We test the D meson wave function by a χ fit with experimental data of six B → DP channels. We give the branching ratios of all the charmed B decay channels, most of which agree with experiments...
