- 論文の詳細を見る
Space-time evolution of the relativistic perfect fluid of quarks and gluons is calculated numerically in three dimensional space with cylindrically symmetric initial condition. In order to assure the computational validity, the total energy and the total entropy are calculated at every step of the evolution with the proper time. The temperature itself decreases rapidly, but the effective temperature, defined by the temperature multiplied by the Lorentz factor in the transverse direction, falls down rather slowly and approaches some asymptotic value. This behavior of the effective temperature suggests that one can get the information on the initial state of the quark-gluon fluid from the experimental p_t distribution of produced hadrons.
