Physics at BES-III

We give a detailed review of the construction of gauge invariant Lagrangians for free and interacting higher spin fields using the BRST approach developed over the past few years.This physics book provides detailed discussions on important topics in

Dynamically generated 0+ heavy mesons in a heavy chiral unitary approach

Study of qqqc\bar c five quark system with three kinds of quark-quark hyperfine interaction

-charm physics that will be explored during the next few years at bes3 . Both theoretical and experimental issues are covered, including extensive reviews of recent theoretical developments and experimental techniques. Among the subjects covered are: innovations in Partial Wave Analysis (PWA), theoretical and experimental techniques for Dalitz-plot analyses, analysis tools to extract absolute branching fractions and measurements of decay constants, form factors, and CP-violation and DzDzb-oscillation parameters. Programs of QCD studies and near-threshold tau-lepton physics measurements are also discussed.

Possible S-wave Bound-States of Two Pseudoscalar Mesons

In terms of the heavy chiral Lagrangian and the unitarized coupled-channel scattering amplitude, interaction between the heavy meson and the light pseudoscalar meson is studied. By looking for the pole of scattering matrix on an appropriate Riemann sheet, a DK bound state D-s0* with the mass of 2.312 +/- 0.041 GeV is found. This state can be associated as the narrow D*(sJ)(2317) state found recently. In the same way, a B (K) over bar bound state B* is found, and its mass of 5.725 +/- 0.039 GeV is predicted. The spectra of D-0* and B-0* with I = 1/2 are further investigated. One broad and one narrow states are predicted in both charm and bottom sectors. The coupling constants and decay widths of the predicted states are also calculated. (c) 2006 Elsevier B.V. All rights reserved.
