Photon Emission
Heavy quark physics is one of the frontier areas in studies of the fundamental properties of matter. That is why a new generation of ee colliders (B-factories) has been designed. The CLEO-III , BELLE , and BABAR 3 experiments are running since 1999. Their main goal is the precise investigation of the CabibboKobayashi-Maskawa matrix and, first of all, CP-violation in the b-quark sector. To achie...
متن کاملPhoton emission in heavy ion collisions at the CERN SPS
We compute the thermal photon spectrum in the Pb+Pb collisions at the CERN SPS energy using thermal emission rates and a hydrodynamic description for the evolution of produced hot matter and compare our results with the measurements of the excess photons by the WA98 collaboration. Our results show that the measured photon spectrum can be reproduced with realistic initial conditions which take p...

متن کاملPhoton emission from a parton gas at chemical nonequilibrium.
We compute the hard photon production rate of a chemically non-equilibrated quark-gluon plasma. We assume that the plasma is already thermally equili-brated, i. e. describable by a temperature, but with a phase-space distribution that deviates from the Fermi/Bose distribution by a time dependent factor (fugacity). The photon spectrum is obtained by integrating the photon rate over the space-tim...
متن کاملDynamics and hadronization at intermediate transverse momentum at RHIC
The ultra-relativistic heavy-ion program at RHIC has shown that at intermediate transverse momenta (pT ≃ 2-6 GeV) standard (independent) parton fragmentation can neither describe the observed baryon-to-meson ratios nor the empirical scaling of the hadronic elliptic flow (v2) according to the number of valence quarks. Both aspects find instead a natural explanation in a coalescence plus fragment...
