Chiral-scale Effective Field Theory for Dense and Thermal Systems

In this contribution, I will present some properties of nuclear matter (NM) using the chiral-scale effective field theory (EFT) anchored in the chiral, scale, and hidden local flavor symmetries of QCD. We show that the sound velocity (SV) of NM can saturate the conformal limit and exhibits a peak configuration in the intermediate density. To extend the chiral-scale EFT to both dense and thermal systems, we establish a chiral-scale density counting (CSDC) rule and explore the contributions up to \(O(k_c¹²)\).
