∆ resonances : quark models , chiral symmetry and AdS / QCD
The mass spectrum of ∆ resonances is compared to predictions based on three quark-model variants, to predictions assuming that chiral symmetry is restored in high-mass baryon resonances, and to predictions derived from AdS/QCD. The latter approach yields a nearly perfect agreement when the confinement property of QCD is modeled by a soft wall in AdS. PACS: 11.25.Tq Gauge/string duality, 11.30.R...
متن کاملElectroexcitation of the Roper resonance in the relativistic quark models
The amplitudes of the transition γ∗N → P11(1440) are calculated within light-front relativistic quark model assuming that the P11(1440) is the first radial excitation of the 3q nucleon state. The results are compared with those obtained in close approaches by other authors and with standard nonrelativistic calculations. One of the reasons for this study was to present all these results within u...
متن کاملNucleon resonances in the constituent quark model with chiral symmetry
The mass spectra of nucleon resonances with spin 1 2 , 3 2 , and 5 2 are systematically studied in the constituent quark model with meson-quark coupling, which is inspired by the spontaneous breaking of chiral symmetry of QCD. The meson-quark coupling gives rise not only to the one-meson-exchange potential between quarks but also to the self-energy of baryon resonances due to the existence of m...
متن کاملThe Nucleon and Roper Resonance in a Chiral Quark Diquark Model
A description of the nucleon and Roper resonance in a quark-diquark approach is presented. We show that two states with the quantum number of the nucleon can appear in the ground state of the spatial configuration, when there are two types of diquarks: scalar-isoscalar and axialvector-isovector diquarks. The mass difference between the two states is generated by the mass difference between the ...
متن کاملRoper Resonance in a Quark-diquark Model
We discuss a new description for the Roper resonance, the first nucleon excited state of JP = 1/2+, in a model of strong diquark correlations. Treating the scalarisoscalar and axial-vector–isovector diquarks as independent degrees of freedom, two states having nucleon quantum numbers are constructed. Due to the scalar and axial-vector nature of the diquarks, the two nucleon states have differen...
