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

High Energy Physics - Phenomenology 2015-05-13 v1

Abstract

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.
