Chiral Symmetry Breaking in a Soft-Wall Model of AdS/QCD
نویسنده
چکیده
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.

Chiral 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 کاملSoft-wall model of AdS/QCD: The case of light scalar mesons
We study light scalar mesons in the AdS/QCD soft-wall model with a background dilaton field, to investigate the features of this approach in describing QCD properties in the strong coupling regime. We find that the masses and decay constants are compatible with experiment and QCD determinations if a0(980) and f0(980) are identified as the lightest scalar mesons; moreover, the states are organiz...
متن کاملMesons and Nucleons in Soft-Wall AdS/QCD with Constrained Infrared Background
The purpose of this paper is to further study the soft-wall AdS/QCD model with constrained IR background proposed in [1]. By including a quartic bulk scalar potential we study various meson and nucleon spectra. This model naturally realizes the asymptotical linearity of these mass spectra simultaneously, together with correctly pattern of explicit and dynamical chiral symmetry breaking. The agr...
متن کاملScalar glueball in a holographic model of QCD
Recently, a lot of interest has grown around the possibility of applying string inspired techniques to the non-perturbative regime of QCD. The starting point is the AdS/CFT correspondence [1], a conjectured duality between a maximally supersymmetric strongly coupled conformal field theory and the supergravity limit of type IIB string theory, which involves theories different from QCD. Further d...
متن کاملOn two-point correlation functions in AdS/QCD
In this paper we study the chiral symmetry breaking in the hard wall AdS/QCD model. We solve the equations of motion up to the second order at large momentum and obtain the first few terms in the expansion of the ”left-right” correlator, which is the measure of symmetry breaking. In the strong coupling calculation we get the result as the series in square root of t’Hooft constant.
