Nucleation of quark-gluon plasma from hadronic matter.
The energy densities achieved during central collisions of large nuclei at Brookhaven’s AGS may be high enough to allow the formation of quark–gluon plasma. Calculations based on relativistic nucleation theory suggest that rare events, perhaps one in every 102 or 103, undergo the phase transition. Experimental ramifications may include an enhancement in the ratio of pions to baryons, a reductio...
متن کاملQuark exchange model for charmonium dissociation in hot hadronic matter.
A diagrammatic approach to quark exchange processes in meson-meson scattering is applied to the case of inelastic reactions of the type (Q ¯ Q) + (q¯ q) → (Q¯ q)+(q ¯ Q), where Q and q refer to heavy and light quarks, respectively. This string-flip process is discussed as a microscopic mechanism for charmonium dissociation (absorption) in hadronic matter. The cross section for the reaction J/ψ ...
متن کاملPhotons 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 کاملOn the Thermodynamics of Hot Hadronic Matter
The equation of state of hot hadronic matter is obtained, by taking into account the contribution of the massive states with the help of the resonance spectrum τ(m) ∼ m3 justified by the authors in previous papers. This equation of state is in agreement with that provided by the low-temperature expansion Bitnet: [email protected] Bitnet: [email protected]. On sabbatical leave from School o...
