Spectroscopy of D Mesons
The scenario of heavy quark meson spectroscopy underwent recently a major revolution, after the observation of BABAR and CLEO, confirmed by BELLE, of DsJ L=1 excited states, and by further evidences by SELEX. These experimental results have cast doubts on the incarnations of the ideas of Heavy Quark Effective Theory in heavy quark spectroscopy. I shall review the status of experimental data, di...
متن کاملSuppressed decays of D(s)(+) mesons to two pseudoscalar mesons.
Using data collected near the D{s}{*+}D{s}{-} peak production energy E_{cm}=4170 MeV by the CLEO-c detector, we study the decays of D{s}{+} mesons to two pseudoscalar mesons. We report on searches for the singly Cabibbo-suppressed D{s}{+} decay modes K{+}eta, K{+}eta', pi{+}K{S}{0}, K{+}pi{0}, and the isospin-forbidden decay mode D{s}{+}-->pi{+}pi{0}. We normalize with respect to the Cabibbo-fa...
متن کامل{ 1{ Note on D Mesons
The new experimental results on charm meson decays reported in this edition are predominantly from CLEO II at the e + e ? storage ring CESR and from xed-target experiments, especially photoproduction experiment E687 at Fermilab. The rst results from the BES experiment, operating at an e + e ? center-of-mass energy of 4.0 GeV, also appear in this edition. BES has measured the branching fractions...
متن کاملHadronic D Decays Involving Scalar Mesons
The nonleptonic weak decays of charmed mesons into a scalar meson and a pseudoscalar meson are studied. The scalar mesons under consideration are σ [or f0(600)], κ, f0(980), a0(980) and K 0 (1430). A consistent picture provided by the data suggests that the light scalars below or near 1 GeV form an SU(3) flavor nonet and are predominately the q2q̄2 states, while the scalar mesons above 1 GeV can...
