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 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 the Nuclear Medium
In this talk I first discuss predictions based on QCD sum rules and on hadronic models for the properties of vector mesons in the nuclear medium. I then describe possible experimental signatures and show detailed predictions for dilepton invariant mass spectra with a special emphasis on nuclear reactions involving elementary incoming beams and nuclear targets. I will in particular illustrate th...
متن کاملHadrons with charmed quarks in matter
We investigate the DD̄ decay width of excited charmonium states at finite nuclear density with simultaneous modification of both D and D̄ mesons in nuclear matter. The strongest effect is found for the Ψ ′ meson. The medium modification can be detected by dilepton spectroscopy as substantial Ψ ′ broadening and anomalous Ψ ′ absorption. PACS. 13.25.Gv Decays of J/Ψ , Υ , and other quarkonia – 14.4...
متن کاملThe Changes in Properties of Hadrons in Nuclei and Nuclear Matter
The changes of hadron properties in dense and/or hot matter are discussed in terms of effective chiral Lagrangians with the parameters of the theory scaled in a simple way. The phenomenologically successful Walecka model is identified as a mean field chiral Lagrangian with the scaled parameters. Kaon condensation and chiral restoration transitions can be described within the same mean field fra...
