hadrondominated
Hadrondominated is a term used in theoretical physics to describe a regime in which hadronic degrees of freedom provide the primary description of a system, with quark and gluon (partonic) contributions playing a subleading role. The concept is often invoked when confinement remains effective and the relevant excitations are hadrons, such as in low- to moderate-temperature or low-density settings.
Formal criteria for hadron dominance are model-dependent but generally involve comparing the contributions of hadronic states
In practice, the term appears in discussions of hadron resonance gas models, chiral effective theories, and
Hadrondominated contrasts with parton-dominated or quark-gluon plasma regimes, where quarks and gluons provide the leading degrees
