Structure of the Lambda(1405) baryon resonance from its large Nc behavior
Tetsuo Hyodo, Daisuke Jido, Luis Roca
We study the behavior with the number of colors (Nc) of the two poles associated to the Lambda(1405) resonance obtained dynamically within the chiral unitary approach. The leading…
Transition form factors of the N*(1535) as a dynamically generated resonance
D. Jido, M. Doering, E. Oset
We discuss how electromagnetic properties provide useful tests of the nature of resonances, and we study these properties for the N*(1535) which appears dynamically generated from…
Photo- and Electron-Production of Mesons on Nucleons and Nuclei
E. Oset, M. Döring, D. Strottman +8
In these lectures I will show some results obtained with the chiral unitary approach applied to the photo and electroproduction of mesons. The results for photoproduction of $ηπ^0…
Exotic hadrons and SU(3) chiral dynamics
Tetsuo Hyodo, Daisuke Jido, Atsushi Hosaka
We explore a possibility to generate exotic hadrons dynamically in the scattering of hadrons. The s-wave scattering amplitude of an arbitrary hadron with the Nambu-Goldstone boson…
In-medium Pions and Partial Restoration of Chiral Symmetry: a model-independent analysis
D. Jido, T. Hatsuda, T. Kunihiro
Exploiting operator relations in QCD, we derive a novel and model-independent formula relating the in-medium quark condensate <bar-q q>* to the decay constant F*_t and the wave fun…
Study of exotic hadrons in s-wave chiral dynamics
Tetsuo Hyodo, Daisuke Jido, Atsushi Hosaka
We study the exotic hadrons in s-wave scattering of the Nambu-Goldstone boson with a target hadron based on chiral dynamics. Utilizing the low energy theorem of chiral symmetry, we…
