Description
The behavior of scale symmetry in dense and thermal systems is an interesting topic in nuclear physics as it relates to the stiffness of equation of state. In this talk, I will discuss the nuclear matter properties by using an effective field theory with respect to the trace anomaly of QCD---chiral scale effective field theory. Explicitly, the pseudoconformal structure, the behavior of sound velocity, and a new power counting scheme convenient for study the meson fluctuation effects.
