The 1/n C Approach for Baryon Resonances
I give a brief overview of the model-independent analysis of unstable baryon resonances in the 1/Nc QCD expansion. This approach produces numerous surprising semi-quantitative phenomenological predictions that are supported by available observations.
متن کاملBaryon Resonances
Identifying a zero-range exchange of vector mesons as the driving force for the s-wave scattering of pseudo-scalar mesons off the baryon ground states, a rich spectrum of molecules is formed. We argue that chiral symmetry and large-Nc considerations determine that part of the interaction which generates the spectrum. We suggest the existence of strongly bound crypto-exotic baryons, which contai...
متن کاملThe search for missing baryon resonances
Experiments with electromagnetic probes are promising to search for baryon resonances that have been predicted by quark models but have not yet been observed. Data sets from different experiments show interesting resonance structures possibly due to so far unknow states. This might indicate that at least some of the missing baryon resonances start to show up. Introduction At medium energies, ou...
متن کاملMeson 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...
