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 کاملMeson-Baryon Effective Chiral Lagrangians to O(q3)
We construct the complete and minimalO(q2) and O(q3) three-flavour Lorentz invariant chiral meson-baryon Lagrangians for the first time in the literature. We compare with previous three-flavour studies reducing the number of independent monomials and adding new ones that were missing.
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 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...
