C. A. Ballon Bayona, Henrique Boschi-Filho, Nelson R. F. Braga

摘要:

利用D3-D 7膜模型研究了有限温度下类空味流在N = 2强耦合超杨-米尔斯等离子体中的传播.部分子对等离子体结构函数的贡献是从延迟电流-电流换向器的虚部得到的。在高温下,我们发现一个非零的结果,为高能量的电流,表明吸收的味道电流的夸克成分的等离子体。在低温下,夸克对等离子体结构函数没有贡献。

英文摘要:

We investigate the propagation of a space-like flavour current in a strongly coupled N = 2 super Yang-Mills plasma using the D3-D7 brane model at finite temperature. The partonic contribution to the plasma structure functions is obtained from the imaginary part of the retarded current-current commutator. At high temperatures we find a non-vanishing result, for a high energy current, indicating absorption of the flavour current by the quark constituents of the plasma. At low temperatures there is no quark contribution to the plasma structure functions.
