∆ resonances : quark models , chiral symmetry and AdS / QCD
نویسنده
چکیده
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.

Chiral Symmetry Breaking in a Soft-Wall Model of AdS/QCD
We incorporate chiral symmetry breaking in a soft-wall version of the AdS/QCD model by using a modified dilaton profile and a quartic term in the bulk scalar potential. This allows one to separate the dependence on spontaneous and explicit chiral symmetry breaking. The resulting mass spectra in the scalar, vector and axial-vector sectors compares favorably with the respective QCD resonances.
متن کاملTensor Mesons in AdS/QCD
We explore tensor mesons in AdS/QCD focusing on f2(1270), the lightest spin-two resonance in QCD. We find that the f2 mass and the partial width Γ(f2 → γγ) are in very good agreement with data. In fact, the dimensionless ratio of these two quantities comes out within the current experimental bound. The result for this ratio depends only on Nc and Nf , and the quark and glueball content of the o...
متن کاملChiral Symmetry Breaking in Soft-Wall AdS/QCD
We show how to incorporate chiral symmetry breaking in the soft-wall version of the AdS/QCD model by using a modified dilaton profile and a quartic term in the bulk scalar potential. This allows one to separate the dependence on spontaneous and explicit chiral symmetry breaking. Moreover our 5D model automatically incorporates linear trajectories and non chiral-symmetry restoration for highly e...
متن کاملChiral symmetry breaking driven by dilaton
A supersymmetric gauge theory with flavor quark is studied in a dual supergravity by adding a D7-brane probe into the AdS background deformed by the dilaton. This background exhibits quark-confinement and gluon condensation in the dual gauge theory. By estimating the vev of flavor quark-bilinear in the gravity dual, we find spontaneous chiral symmetry breaking and simultaneous supersymmetry bre...
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...
