Hidden and open charm at Belle (and elsewhere)
There have been great advances in charm physics at the B-factories in recent years, including the observation of D-D 0 mixing and the discovery of many new hidden-charm states, some of them presumably exotic in structure. This talk reviews some of the recent Belle results, with emphasis on the hidden-charm sector. Evidence for two new charged states is presented for the first time at this confe...
متن کاملDecays to Open and Hidden Charm at Belle
The recent Belle collaboration measurements of B decays to open and hidden charm are discussed. Color-suppressed decay branching fractions are measured with an improved accuracy. The branching fractions of the B̄0 → D s K − and B̄0 → D− s π + decays, measured with improved accuracy, and B̄0 → D sJ K and B̄0 → D− sJ π+ decays, measured for the first time, are compared. The two-body invariant masses ...
متن کاملCharm at Belle
With 10fb −1 data from Belle, the results of b to c and u decays have been represented here. Several decay modes have been studied, which include charmonium, semileptonic decay and Cabibbo-suppressed decays mode. The preliminary results and the measurements of KM matrix elements will also be presented here.
متن کاملNew Open and Hidden Charm Spectroscopy
Many new results on open and hidden charm spectroscopy have been obtained recently. We present a short review of the experimental findings in the meson sector, of the theoretical interpretations and of the open problems, with a discussion on the possibility that some mesons are not quark-antiquark states.
متن کاملAxial Resonances in the Open and Hidden Charm Sectors
A SU(4) flavor symmetrical Lagrangian is constructed for the interaction of the pseudo-scalar mesons with the vector mesons. SU(4) symmetry is broken to SU(3) by suppression of terms in the Lagrangian where the interaction should be driven by charmed mesons. Chiral symmetry can be restored by setting this new SU(4) symmetry breaking parameters to zero. Unitarization in coupled channels leads to...
