Abstract: (Elsevier)
We study scenarios for chiral symmetry restoration and deconfinement at finite temperature and/or density, based on assuming universal scaling relations fort some hadron masses. We explore and discuss consequences of this scaling assumption in nuclear structure and show that most experiments support the scaling. The relevance of soft and hard scales as pertaining to chiral symmetry restoration and deconfinement is emphasized, and scaling relations for nonstrange and strange Goldstone bosons are presented. Theoretical support for the scaling relations is found from the analysis of effective Lagrangians in hot and dense matter, as well as finite-temperature and finite-density QCD sum rules. Both approaches suggest the validity of approximate scaling relations and identify sources of violation of the latter.
