摘要:

本文计算了$\sqrt{s_{NN}}=19-200$ ~GeV的Au-Au碰撞中的瞬发和热光子产生。我们讨论了电磁辐射相关的等离子体的时空轮廓的功能。我们强调如何抑制在低$\sqrt{s_{NN}}$的即时光子产生可以提供一个窗口,以测量在低碰撞能量的热光子。

英文摘要:

We present calculations of prompt and thermal photon production in Au-Au collisions at $\sqrt{s_{NN}}=19-200$~GeV. We discuss features of the spacetime profile of the plasma relevant for electromagnetic emission. We highlight how the suppression of prompt photon production at low $\sqrt{s_{NN}}$ can provide a window to measure thermal photons in low collision energies.
