Abstract

In this talk, chiral scale, 4πfπ∼1GeV, was introduced as an indicator of partial restoration of chiral symmetry at finite density or temperature, rather than the argument between mass shift and collisional broadening. We use the finite energy sum rules to determine the chiral scale identified with the separation scale of the low-energy resonance part from the high-energy continuum part of ρ-meson spectral function. In this framework, in-medium ρ-meson mass should be discussed in terms of the first two moments of the spectral function.
