Vector mesons in dense matter
We will summarize the progress in understanding the changes in the vector meson spectral density in nuclear medium using the constraint equations obtained from the Borel transformed dispersion relation and QCD Operator Product Expansion. We will discuss the results for the scalar mass shift and dispersion effects (three momentum dependence) for the light quark system (ρ, ω), the strange quark s...
متن کاملVector mesons in a hot pion gas
Previous selfconsistent approximation studies [1, 2] for the description of hadrons in hot and dense matter were extended along several lines [3, 4]. These concern the inclusion of the real parts of all polarisation functions by appropriately subtracted dispersion relations and of RPA-type π-ρ – meson correlations, which also lead to corresponding vertex corrections. Thus we arrive at a system ...
متن کاملVector Mesons and Dense Skyrmion Matter
In our continuing effort to understand hadronic matter at high density, we have developed a unified field theoretic formalism for dense skyrmion matter using a single Lagrangian to describe simultaneously both matter and meson fluctuations and studied in-medium properties of hadrons. Dropping the quartic Skyrme term , we incorporate into our previous Lagrangian the vector mesons ρ and ω in a fo...
متن کاملMedium 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 کاملDense and Hot Holographic QCD: Finite Baryonic E Field
We investigate the response of dense and hot holographic QCD (hQCD) to a static and baryonic electric field E using the chiral model of Sakai and Sugimoto. At zero temperature, the dense state is an insulator for very weak external baryonic fields E. Strong fields with E > ( √ λMKK) 2 free quark pairs, causing the confined vacuum and matter state to decay. We generalize Schwinger’s QED persiste...
