We review the recent status of the QCD sum rule approach to study the properties of
hadrons in vacuum and in hot or dense matter. Special focus is laid on the progress made in …

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 …

I make two comments about nuclear matter. First, I consider the effects of a coupling
between the O (4) chiral field, ϕ→, and the ω μ meson,∼+ ϕ→ 2 ω μ 2; for any net baryon …

The excitation function and momentum distribution of η′ mesons have been measured in
photoproduction off Nb 93 in the energy range of 1.2–2.9 GeV. The experiment has been …

An experimental study of ω photoproduction on the proton was conducted by using the
Crystal Ball and TAPS multiphoton spectrometers together with the photon tagging facility at …

The photoproduction of ω and η^′ mesons off carbon and niobium nuclei has been
measured as a function of the meson momentum for incident photon energies of 1.2-2.9 GeV …

The production of η^′ η mesons in coincidence with forward-going protons has been
studied in photon-induced reactions on 12 C and on a liquid hydrogen (LH 2) target for …

As an improvement of the QCD sum rule method to study modifications of light vector
mesons in nuclear matter and/or at finite temperature, we calculate the Wilson coefficients of …

We study ΛK+ pair production in the interaction of protons of 2.83 GeV kinetic energy with C,
Cu, Ag, and Au target nuclei in the framework of the nuclear spectral function approach for …

The intranuclear cascade model INCL (Liège Intranuclear Cascade) is now able to simulate
spallation reactions induced by projectiles with energies up to roughly 15 GeV. This was …
