摘要

Properties of hadrons in nuclear medium is interest in studying the Quantum Chromodynamics (QCD) structure in dense matter, in particular related to the chiral symmetry restoration, phase-transition from quark-gluon plasma to hadrons, dynamics of hypernucleus formation, nuclear equation of state (EoS), etc. High energy heavy-ion collisions in terrestrial laboratory provide a unique possibility to study the in-medium properties of hadrons in dense nuclear matter and to extract the high-density behavior of the nuclear symmetry energy (isospin asymmetri part of EoS). The dynamics of pseudoscalar mesons in heavy-ion collisions and the in-medium properties in dense nuclear matter have been investigated with the Lanzhou quantum molecular dynamics (LQMD) transport model[1].
