In-medium effects on electromagnetic probes
We discuss some of the aspects of the physics of relativistic nuclear collisions, in particular those having to do with the observation of electromagnetic radiation. We concentrate on what such measurements tell us about the local, in-medium properties of the environment from which they emerge. The contribution from different sources are considered: that from the partonic sector of QCD, and tha...
متن کاملExploring the LHC medium with electromagnetic probes
Heavy-ion collisions will enter a new era with the start of the CERN Large Hadron Collider (LHC). A first short run with proton-proton collisions at the injection energy of 0.9 TeV will be followed by a longer one with pp collisions at 10 TeV. First Pb-Pb collisions at √ sNN=5.5 TeV will take place in 2009. Three experiments (ALICE, ATLAS, and CMS) will study both pp and Pb-Pb collisions. A sel...
متن کاملHadronic In-medium Effects with Elementary Probes
The sensitivity of dilepton production in elementary reactions of photons and pions with nuclei on in-medium changes of hadronic properties is studied. It is shown that this sensitivity is comparable to that encountered in ultrarelativistic heavy-ion collisions. It is also shown how a significant broadening of the vector mesons affects other photonuclear processes.
متن کاملElectromagnetic Radiation and in - Medium Effects
The theory of thermal photon and dilepton emission from hot and dense hadronic matter, as well as from the Quark-Gluon Plasma, is reviewed in the context of extracting in-medium properties of the matter constituents. In phenomenological applications to ultrarelativistic heavy-ion collisions we focus on low transverse-momentum ”anomalies” as recently observed in photon and dilepton spectra by WA...
متن کاملElectromagnetic Probes
A review is presented of dilepton and real photon measurements in relativistic heavy ion collisions over a very broad energy range from the low energies of the BEVALAC up to the highest energies available at RHIC. The dileptons cover the invariant mass range ml+l− = 0 2.5 GeV/c, i.e. the continuum at low and intermediate masses and the light vector mesons, ρ, ω, φ. The review includes also meas...
