Direct photons ~basis for characterizing heavy ion collisions~
arXiv:0805.4644 · doi:10.1088/0954-3899/35/10/104025
Abstract
After years of experimental and theoretical efforts, direct photons become a strong and reliable tool to establish the basic characteristics of a hot and dense matter produced in heavy ion collisions. The recent direct photon measurements are reviewed and a future prospect is given.
