Photons from Quark Gluon Plasma and Hot Hadronic Matter
The productions of real photons from quark gluon plasma and hot hadronic matter formed after the nucleus nucleus collisions at ultra-relativistic energies are discussed. The effects of the spectral shift of the hadrons at finite temperature on the production of photons are investigated. On the basis of the present analysis it is shown that the photon spectra measured by WA98 collaboration in Pb...
متن کاملDual magnetic mass of a hot quark-gluon plasma.
The dual magnetic mass of a hot quark-gluon plasma is computed in the lowest order of dual QCD, which predicts a well-defined (dual) gauge-invariant result for it. This is because, in dual QCD, electricity and magnetism are interchanged, so magnetic calculations in dual QCD are easy if the corresponding electric ones in ordinary QCD are easy, and vice versa. We obtain the (leading-order) numeri...
متن کاملEnergy and pressure densities of a hot quark-gluon plasma.
We calculate the energy and hydrostatic pressure densities of a hot quark-gluon plasma in thermal equilibrium through diagrammatic analyses of the statistical average, h i, of the energy-momentum-tensor operator . To leading order at high temperature, the energy density of the long wave length modes is consistently extracted by applying the hard-thermal-loop resummation scheme to the operatorin...
متن کاملDiscovery of Quark Gluon Plasma at RHIC
Recent experimental results from Relativistic Heavy Ion Collider (RHIC) have shown the evidence of a new state of matter at high energy density. Physicists believe that the new state of matter is "Quark Gluon Plasma"(QGP) that they have been seeking for long time. This paper will survey both theoretical and experimental studies on QGP.
متن کاملThe quark-gluon plasma at RHIC
I present a theory-guided review of RHIC data, arguing that they provide strong evidence for formation of a thermalized quark-gluon plasma at RHIC. Strong radial flow reflects high thermal pressure in the reaction zone. Large elliptic flow proves that the pressure builds up quickly and the system thermalizes on a very short time scale of < 1 fm/c. The observed hadron yields are consistent with ...
