Enhancement of low-mass dileptons in heavy ion collisions.
TL;DR: Using a relativistic transport model for the expansion stage of S+Au collisions at 200 GeV/nucleon, it is shown that the recently observed enhancement of low-mass dileptons by the CERES Collaboration can be explained by the decrease of vector meson masses in hot and dense hadronic matter.

The role of nucleon structure in finite nuclei
TL;DR: In this article, the quark-meson coupling model, based on a mean field description of nonoverlapping nucleon bags bound by the selfconsistent exchange of σ, ω and ϱ mesons, is extended to investigate the properties of finite nuclei.

Nucleon and hadron structure changes in the nuclear medium and the impact on observables
TL;DR: In this paper, the effect of hadron structure changes in a nuclear medium using the quark-meson coupling (QMC) model is studied, which is based on a mean field description of non-overlapping nucleon (or baryon) bags bound by the self-consistent exchange of scalar and vector mesons in the isoscalar and isovector channels.

TL;DR: The change of hadron properties in dense matter based on various theoretical approaches are reviewed in this paper, which provides satisfactory explanations for the observed enhancement of kaon, antikaon and antiproton yields in the transverse direction from the SIS experiments.

Variation of hadron masses in finite nuclei
TL;DR: In this article, the quark-meson coupling model was extended to investigate the change of hadron properties in finite nuclei, and a simple scaling relation for the changes of the hadron masses was found, which can be described in terms of the number of nonstrange quarks in a hadron and the value of the scalar mean field in a nucleus.

TL;DR: In this paper, a systematic study is made of the non-perturbative effects in quantum chromodynamics, where the basic object is the two-point functions of various currents and the terms of this series are shown to be of two distinct types.

A theory of highly condensed matter
TL;DR: In this article, a model relativistic, many-body, quantum field theory composed of a baryon field, a neutral scalar meson field coupled to the scalar density ψ ψ, and a neutral vector meson fields coupled with the conserved Baryon current i Ψ γλψ is developed.

TL;DR: The approximate {ital in}{minus}{ital medium} scaling law is established, which has a highly nontrivial implication for nuclear processes at and above nuclear-matter density.
