In this review we first outline the basics of transport theory and its recent generalization to off-
shell transport. We then present in some detail the main ingredients of any transport method …

The QCD vacuum shows the dynamical breaking of chiral symmetry. In the hot and/or dense
QCD medium, the chiral order parameter such as⟨ q¯ q⟩ is expected to change as a …

Recent experiments studying the meson–nucleus interaction to extract meson–nucleus
potentials are reviewed. The real part of the potentials quantifies whether the interaction is …

A quantitative evaluation of dilepton sources in heavy-ion reactions is performed taking into
account both thermal and non-thermal production mechanisms. The hadronic thermal …

We review the current status of theories and experiments aiming at an understanding and a
determination of the properties of light vector and scalar mesons inside strongly interacting …

Information on hadron properties in the nuclear medium has been derived from the
photoproduction of ω mesons on the nuclei C, Ca, Nb, and Pb using the Crystal Barrel/TAPS …

The photoproduction of η′-mesons off different nuclei has been measured with the
CBELSA/TAPS detector system for incident photon energies between 1500–2200 MeV. The …

The production of η and η′ mesons in photon-and hadron-induced reactions on free and
quasi-free nucleons and on nuclei is reviewed. The extensive database on γ N→ η N, for …

After some short introductory remarks on particular issues on the vector mesons in nuclei, in
this paper, we present a short review of recent developments concerning the interaction of …

Data on the photoproduction of ω mesons on nuclei have been reanalyzed in a search for in-
medium modifications. The data were taken with the crystal barrel (CB)/two-arm photon …
