摘要: A self-consistent dynamical soft-wall holographic QCD model is formulated in the framework of graviton-dilaton-scalar system, which can realize both chiral symmetry breaking and confinement, two most important phenomena QCD. The scalar field corresponds to quark-antiquark condensate explain property dynamics. quadratic dilaton background phi = mu(2)z(2) as original accommodate aspects manifestation color i.e. Regge spectra hadrons linear potential between quarks. It observed that slope string tension quark are proportional mu(2). More interesting observation best fitted value mu around gluon mass extracted from lattice data. also shown negative be safely excluded this framework.
