Dileptons from a Quark Gluon Plasma with Finite Baryon Density
We investigate the effects of a baryon-antibaryon asymmetry on the spectrum of dileptons radiating from a quark gluon plasma. We demonstrate the existence of a new set of processes in this regime. The dilepton production rate from the corresponding diagrams is shown to be as important as that obtained from the usual quark-antiquark annihilation. 25.70.Np, 12.38.Cy, 12.38.Mh Typeset using REVTEX 1
متن کاملChemical equilibration and thermal dilepton production from the quark gluon plasma at finite baryon density
The chemical equilibration of a highly unsaturated quark-gluon plasma has been studied at finite baryon density. It is found that in the presence of small amount of baryon density, the chemical equilibration for gluon becomes slower and the temperature decreases less steeply as compared to the baryon free plasma. As a result, the space time integrated yield of dilepton is enhanced if the initia...
متن کاملBaryon-Strangeness Correlations from Hadron/String- and Quark-Dynamics
Baryon-strangeness correlations (CBS) are studied with a hadron/string transport approach (UrQMD) and a dynamical quark recombination model (quark molecular dynamics, qMD) for various energies from Elab = 4A GeV to √ sNN = 200 GeV. As expected, we find that the hadron/string dynamics shows correlations similar to a simple hadron gas. In case of the quark molecular dynamics, we find that initial...
متن کاملBaryon Density and the Dilated Chiral Quark Model
We calculate perturbatively the effect of density on hadronic properties using the chiral quark model implemented by the QCD trace anomaly. We calculate the density dependent masses of the constituent quark (mQ), the scalar field (mχ) and the pion (mπ) in oneloop order using the technique of thermo field dynamics. In the chiral limit, the pion remains massless at finite density. It is found tha...
متن کاملBaryon Number Fluctuation and the Quark-Gluon Plasma
Because of the fractional baryon number of quarks, baryon and antibaryon number fluctuations in the quark-gluon plasma is less than those in the hadronic matter, making them plausible signatures for the quark-gluon plasma expected to be formed in relativistic heavy ion collisions. To illustrate this possibility, we have introduced a kinetic model that takes into account both production and anni...
