Medium Modifications of Vector Mesons and NA60
We confront different models for medium modifications of the electromagnetic correlation function to recent dimuon spectra from the NA60 collaboration for central In-In collisions at the CERN-SPS. In the low-mass region (M.1.0 GeV), we evaluate medium modifications of the spectral properties of ρ-, ωand φ-mesons. In the intermediate-mass region (M>1.0 GeV), we employ schematic models for the mi...
متن کاملIn-Medium Properties of Vector Mesons in Elementary Nuclear Reactions
While the vacuum properties of most hadrons are known to reasonable accuracy today, it is a much-debated question how these properties change in nuclear matter. In particular for the light vector mesons there have been various theoretical predictions regarding their in-medium properties. One of the expected in-medium effects is the so-called ’collisinal broadening’ of the meson spectral functio...
متن کاملVector Mesons in Medium and Dileptons in Heavy-Ion Collisions
The investigation of hadron properties inside atomic nuclei constitutes one of the traditional research objectives in nuclear physics. However, in terms of the underlying theory of strong interactions QCD) even the description of the nuclear ground state remains elusive so far. Valuable insights can be expected from a careful study of transition regimes between hadronic and quark-gluon degrees ...
متن کاملOn Qcd Sum Rules for Vector Mesons in Nuclear Medium *
Vector mesons show up in the electromagnetic current-current correlator. QCD sum rules provide a constraint on hadronic models for this correlator. This constraint is discussed for the case of finite nuclear density concerning the longitudinal as well as the transverse part of the current-current correlator at finite three-momentum. PACS numbers: 24.85.+p, 21.65.+f, 12.38.Lg, 14.40.Cs
متن کاملTheory and Phenomenology of Vector Mesons in Medium
Electromagnetic probes promise to be direct messengers of (spectral properties of) hot and dense matter formed in heavy-ion collisions, even at soft momentum transfers essential for characterizing possible phase transitions. We examine how far we have progressed toward this goal by highlighting recent developments, and trying to establish connections between lattice QCD, effective hadronic mode...
