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 Hot and Dense Matter
The description of excitations in hot and dense (hadronic) matter is discussed with emphasis on the use of correlation functions as a common framework for comparing different model (and QCD lattice) calculations with each other. Typical regimes of applicability of hadronic approaches are assessed, together with possibilities to confront them with experiment. We also elaborate on recent developm...
متن کاملProbing Dense Matter with Strange Hadrons
The signature of quark-gluon plasma is hard to identify, since the final state observed in the laboratory always consists of the same particles, irrespective of the transitional presence of the deconfined state. What changes is the detailed composition of the observed produced particle abundance. We consider here strangeness , and the pattern of strange hadron production at SPS and RHIC which o...
متن کاملHadrons in Dense Resonance - Matter : A Chiral SU ( 3 ) Approach
A nonlinear chiral SU(3) approach including the spin 3 2 decuplet is developed to describe dense matter. The coupling constants of the baryon resonances to the scalar mesons are determined from the decuplet vacuum masses and SU(3) symmetry relations. Different methods of mass generation show significant differences in the properties of the spin2 particles and in the nuclear equation of state. T...
