Pion and thermal photon spectra as a possible signal for a phase transition.

چکیده
We calculate thermal photon and neutral pion spectra in ultrarel-ativistic heavy-ion collisions in the framework of three-fluid hydrody-namics. Both spectra are quite sensitive to the equation of state used. In particular, within our model, recent data for S + Au at 200 AGeV can only be understood if a scenario with a phase transition (possibly to a quark-gluon plasma) is assumed. Results for Au+Au at 11 AGeV and P b + P b at 160 AGeV are also presented.

Critical Scattering and Two Photon
At the Mott transition of a quark/meson plasma, mesons become un-bound. This leads to the eeect of critical scattering, which is studied by investigating photon pair production due to the process q q !. This process can proceed either via direct annihilation or via the formation of a mesonic resonance. It is shown that the latter channel leads to an enhancement of photon pairs with invariant ma...
متن کاملThermal photon production in high-energy nuclear collisions.
We use a boost-invariant one-dimensional (cylindrically symmetric) fluid dynamics code to calculate thermal photon production in the central rapidity region of S+Au and Pb+Pb collisions at SPS energy ( √ s = 20 GeV/nucleon). We assume that the hot matter is in thermal equilibrium throughout the expansion, but consider deviations from chemical equilibrium in the high temperature (deconfined) pha...

متن کاملAnomalous Pseudoscalar-photon Vertex in and out of Equilibrium
The anomalous pseudoscalar-photon vertex is studied in real time in and out of equilibrium in a constituent quark model. The goal is to understand the in-medium modifications of this vertex, exploring the possibility of enhanced isospin breaking by electromagnetic effects as well as the formation of neutral pion condensates in a rapid chiral phase transition in peripheral, ultrarelativistic hea...
متن کاملHard Thermal Photon Production in Relativistic Heavy Ion Collisions
The recent status of hard thermal photon production in relativistic heavy ion collisions is reviewed and the current rates are presented with emphasis on corrected bremsstrahlung processes in the quark-gluon plasma (QGP) and quark-hadron duality. Employing Bjorken hydrodynamics with an EOS supporting the phase transition from QGP to hot hadron gas (HHG), thermal photon spectra are computed. For...
