Exotic states of matter in heavy meson decays 1
The decays of mesons containing heavy quarks provide carefully controlled environments for production of hadronic states with specific quantum numbers. Copious samples of such mesons accumulated at the BaBar, Belle, and CLEO detectors permit searches for interesting forms of matter, including mesons beyond the usual quark-antiquark and baryons beyond the usual three-quark configurations. Such h...
متن کاملOn the dominance of non-exotic meson-meson scattering by s-channel qq̄ confinement states and the classification of the scalar mesons
Non-exotic scalar-meson resonances in S-wave meson-meson scattering are studied in the light of a unitarised Schrödinger model. The resulting poles in the scattering matrices, by analytical continuation into the complex-energy plane, are grouped into nonets of isoscalar, isodoublet, and isotriplet resonances. All singularities can be related to quark-antiquark confinement states, the light-quar...

The feasibility of using the Jefferson Lab. CLAS detector to study peripheral photoproduction of exotic meson is examined.
متن کاملScalar Meson Photoproduction
The light-quark non-strange scalar mesons a0(980), f0(980), f0(1370), a0(1450), f0(1500) and f0(1710) are of great interest as there is no generally accepted view of their structure which can encompass qqq̄q̄, molecular, qq̄ and glueball states in various combinations. It has been shown previously that the radiative decays of the scalar mesons to ρ and ω are a good probe of their structure and pro...
متن کاملLight scalar meson spectrum
We discuss the classification of the light scalar mesons with mass below 2 GeV into qq̄ nonets and glueballs. The information on production and decay of these states, in particular recent information on the f0(980), f0(400−1200) (or σ(600)) and f0(1500) is considered. Although the data are not yet very precise the recent information is in favour of the previously developed scheme which includes ...
