强耦合等离子体的亮膜

Bright branes for strongly coupled plasmas

David Mateos, Leonardo Patino

摘要:

利用全息技术研究了一类有限温度、强耦合、大Nc SU(Nc)夸克-胶子等离子体中的光子产生,其中Nf << Nc夸克味.我们的结果在电磁耦合常数中对首阶有效,但在SU(Nc)相互作用中对非微扰有效。电磁流和其他相关观测量的谱函数作为光子频率和夸克质量的函数呈现出有趣的结构。我们讨论了重离子碰撞实验的可能影响。

英文摘要:

We use holographic techniques to study photon production in a class of finite temperature, strongly coupled, large-Nc SU(Nc) quark-gluon plasmas with Nf << Nc quark flavours. Our results are valid to leading order in the electromagnetic coupling constant but non-perturbatively in the SU(Nc) interactions. The spectral function of electromagnetic currents and other related observables exhibit an interesting structure as a function of the photon frequency and the quark mass. We discuss possible implications for heavy ion collision experiments.
