19 Sep 2000 | | Journal: | Phys.Rev. D63 (2001) 051702 | | Subject: | hep-ph cond-mat nucl-th | | Abstract: | Photon production from a thermalized quark-gluon plasma of finite lifetime is studied directly in real time with a nonequilibrium formulation that includes off-shell (energy nonconserving) effects. To lowest order we find that production of direct photons form a quark-gluon plasma of temperature T ~ 200 MeV and lifetime t ~ 10-20 fm/c is strongly enhanced by off-shell (anti)quark bremsstrahlung q(ar{q})->q(ar{q})gamma. The yield from this nonequilibrium finite-lifetime effect dominates over those obtained from higher order equilibrium rate calculations in the range of energy E > 2 GeV and falls off with a power law for E >> T. | | Source: | arXiv, hep-ph/0009215 | | Services: | Forum | Review | PDF | Favorites | |
