Meson and Baryon resonances
In this talk I review recent advances on the structure of the meson and baryon resonances which can be dynamically generated from the interaction of mesons or mesons and baryons. Particular emphasis is put on results involving vector mesons, which bring new light into the nature of some of the observed higher mass mesons and baryons and make predictions for new states.
متن کاملMeson-baryon interactions and baryon resonances
Meson-baryon interactions are the fundamental building blocks to study the structures of baryon resonances and meson properties in few-body nuclear systems. We review the recent progress in the investigation of the meson-baryon interaction in the strangeness S “ ́1 sector and the structure of the Λp1405q resonance. In particular, we present an attempt to construct a realistic KN-πΣ interaction i...
متن کاملDynamical Meson-baryon Resonances with Chiral Lagrangians
The s-wave meson-baryon interaction is studied using the lowest-order chiral Lagrangian in a unitary coupled-channels Bethe-Salpeter equation. In the strangeness S = −1 sector the low-energy K−p dynamics leads to the dynamical generation of the Λ(1405) as a K̄N state, along with a good description of the K−p scattering observables. At higher energies, the Λ(1670) is also found to be generated dy...
متن کاملVector Meson Decay of Baryon Resonances
One of the evidences for the discovery of a new state of matter that was quoted by the CERN press release in 2000 was the result of the CERES experiment that showed an excess of dileptons at invariant masses below the vector meson mass. In order to understand this phenomenon it is essential to consider the effect of conventional hadronic interactions on the vector mesons. We emphasize the relev...
متن کاملPseudoscalar Meson and Charmed Baryon Scattering Lengths
Up to now many heavy hadrons have been discovered experimentally. Their inner structures and interactions attract much attention. Some of them are speculated to be possible new hadron states beyond the traditional quark model. For example, the newly discovered Zb states are treated as the B̄ (∗)B∗ molecular states [1, 2]. Many other molecular states, such as those composed of ΞcΞc, DD̄ ∗, are als...
