Hadrons in Dense Matter
Physical reason behind the mass-shift of vector mesons (ρ, ω, φ) in nuclear matter is discussed in the Walecka model and in QCD sum rules. Using analytic formulas for the mass-shift valid at low densities, it is shown that the energy dependent part of the self-energy in medium (wave function renormalization) is a main source for the negative massshift, while the energy independent part (the pla...
متن کاملHadrons in Medium – Observables
The observable consequences of a lowering of the restmasses of vector mesons on dilepton spectra in the SIS energy regime (HADES) and on photoabsorption cross sections on nuclei are studied in a transporttheoretical framework. We also investigate the consequences of a mass-shift of kaons in dense matter and compare with recent SIS data. The need for a detailed understanding of the elementary pr...
متن کاملHadrons in Medium
Studies of in-medium properties of hadrons are driven by a number of partly connected motivations. A first motivation for the study of hadronic in-medium properties is provided by our interest in understanding the structure of large dense systems, such as the interior of stars. This structure obviously depends on the composition of stellar matter and its interactions (for a recent review see [1...
متن کاملHadrons in Dense Matter
There is currently enormous interest in the investigation of how hadron properties may be altered by immersion in matter. There is strong evidence of a reduction in the mass of the rho meson from relativistic heavy ion collisions as well as a hint from a recent experiment on photoproduction in light nuclei. We briefly review the main theoretical ideas which lead one to expect the mass of a hadr...
متن کاملHadrons in Nuclei
Changes of hadronic properties in dense nuclear matter as predicted by theory have usually been investigated by means of relativistic heavy-ion reactions. In this talk I show that observable consequences of such changes can also be seen in more elementary reactions on nuclei. Particular emphasis is put on a discussion of photonuclear reactions; examples are the dilepton production at ≈ 1 GeV an...
