论文摘要
大细胞核的超幼体碰撞产生了纯净的夸克和胶子的短寿命等离子体。在这些核碰撞中检测到的所有GEV - 能量光子中，只有少量由Quark-Gluon等离子体发射。我们使用这些光子的特征近指数能谱来估计血浆的最高温度，假设它经历了流体动力膨胀。我们将非指数校正量化为核物质状态和光子排放速率产生的光子光谱。
Ultrarelativistic collisions of large nuclei produce a short-lived plasma of deconfined quarks and gluons. Of all the GeV-energy photons detected in these nuclear collisions, only a small number are emitted directly by the quark-gluon plasma. We use the characteristic near-exponential energy spectrum of these photons to estimate the maximum temperature of the plasma, assuming it undergoes hydrodynamic expansion. We quantify non-exponential corrections to the photon spectrum resulting from the characteristic equation of state and photon emission rate of nuclear matter.
