Spectroscopy and Strong Decays of Charmed Baryons
In the past years many new excited charmed baryon states have been discovered by BaBar, Belle and CLEO. In particular, B factories have provided a very rich source of charmed baryons both from B decays and from the continuum ee → cc̄. A new era for the charmed baryon spectroscopy is opened by the rich mass spectrum and the relatively narrow widths of the excited states. Experimentally and theore...
متن کاملSemileptonic decays of pseudoscalar mesons to scalar f0 meson
The transition form factors of Ds → f0lν, D → f0lν and Bu → f0lν decays are calculated in 3–point QCD sum rule method, assuming that f0 is a quark–antiquark state with a mixture of strange and light quarks. The branching ratios of these decays are calculated in terms of the mixing angle. e-mail: [email protected] permanent address:Institute of Physics,Baku,Azerbaijan e-mail: [email protected]
متن کاملSemileptonic decays of heavy tetraquarks.
There exist heavy tetraquark states QQq̄q̄ in the heavy quark limit. These states are stable with respect to strong interactions and hence must decay weakly. It is shown that the semileptonic decay depends on a single Isgur– Wise form factor, which can be expressed in term of the Isgur–Wise form factors which govern the semileptonic decays of the Qqq and QQq baryons. Typeset using REVTEX 1 The po...
متن کاملStrong decays of strange charmed P-wave mesons.
Goldstone boson decays of P-wave D s mesons are studied within the framework of Heavy Hadron Chiral Perturbation Theory. We first analyze the simplest single kaon decays of these strange charmed mesons. We derive a model independent prediction for the width of Ds2 and use experimental information on Ds1 to constrain the S-wave contribution to D 1 decay. Single and double pion decay modes are th...
متن کاملCharmed baryon strong decays in a chiral quark model
Charmed baryon strong decays are studied in a chiral quark model. The data for the decays of c 2593 , c 2625 , ; ;0 c , and ;0 c 2520 are accounted for successfully, which allows one to fix the pseudoscalar-meson-quark couplings in an effective chiral Lagrangian. Extending this framework to analyze the strong decays of the newly observed charmed baryons, we classify that c 2880 and c 2940 as D-...
