Conformal symmetry breaking in holographic QCD

Understand

In this paper, we investigate a simple holographic model which describes the conformal symmetry breaking at zero temperature.

• The model is implemented in the context of effective holographic models for QCD described by the Einstein-dilaton equations.
• The realization of spontaneous conformal symmetry breaking shows a massless state in the spectrum.
• The existence of this state is confirmed when we compute the two-point correlation function of the scalar operator in the dual field theory, where it has a pole.
