A dynamical holographic QCD model for chiral symmetry breaking and linear confinement

Understand

A self-consistent holographic QCD model is proposed which can realize both chiral symmetry breaking and confinement, two most important phenomena of QCD.

• It is pointed out that the model can accommodate both Regge spectra of hadrons and the linear potential between quarks.
• The model is formulated in the framework of graviton-dilaton-scalar system, where the dilaton field is dual to the dimension-2 gluon condensate and can lead to the linear confinement, while the scalar field corresponds to the quark anti-quark condensate and can explain the property of chiral dynamics.
