Properties of Orbitally Excited Heavy-Light Mesons
نویسندگان
چکیده
Orbitally excited heavy-light mesons are potentially important as tools for tagging the flavors and momenta of ground-state pseudoscalars detected through weak decays. We use heavy-quark symmetry supplemented by insights gleaned from potential models to estimate masses and widths of p-wave B, Bs, and Ds mesons. We generalize these results to higher excitations.

2 00 6 Two topics for a discussion on the bs̄ and bq̄ systems
The analysis of the b¯ s system is an important issue in the Physics programs of the hadron colliders. We discuss two different topics: the structure of the orbitally excited states and prediction of the rates of a class of non leptonic Bs decays. Experiments at the hadron colliders can analyze different aspects of the heavy meson systems, both in the strong, both in the weak sector. For such s...
متن کاملExcited heavy baryons in the bound state picture.
The orbitally excited heavy quark baryons are studied in the Callan Klebanov bound state model with heavy spin symmetry. First, a compact description of the large Nc, infinite heavy quark mass bound state wavefunctions and the collective quantization is given. In order to study the kinematical corrections due to finite masses we motivate an approximate Schrodinger-like equation for the bound st...
متن کاملDissociation cross sections of ground-state and excited charmonia with light mesons in the quark model
We present numerical results for the dissociation cross sections of ground-state, orbitallyand radially-excited charmonia in collisions with light mesons. Our results are derived using the nonrelativistic quark model, so all parameters are determined by fits to the experimental meson spectrum. Examples of dissociation into both exclusive and inclusive final states are considered. The dissociati...

Results from the four LEP experiments ALEPH, DELPHI, L3, and OPAL on the spectroscopy of B and charmed mesons are presented. The predictions of Heavy Quark Effective Theory (HQET) for the masses and the widths of excited L = 1 B mesons are supported by a new measurement from L3. A few Bc candidate events have masses consistent with the recent CDF observation and the predictions. New results on ...

This is a second paper describing the calculation of spectroscopy for orbitally excited states from lattice simulations of Quantum Chromodynamics. New features include higher statistics for P-wave systems and first results for the spectroscopy of D-wave mesons and baryons, for relatively heavy quark masses. We parameterize the Coulomb gauge wave functions for P-wave and D-wave systems and compa...
