非阿贝尔等离子体的完全非线性激发

Fully nonlinear excitations of non-Abelian plasma

Vishnu M. Bannur

摘要:

本文利用冷等离子体近似下的相对论流体理论,研究了夸克-反夸克等离子体的完全非线性、非阿贝尔激发。在我们的模型中,主要有三个重要的非线性,它们来自不同的来源,如Yang-Mills(YM)场的非阿贝尔相互作用、Wong的色动力学和等离子体非线性。通过忽略由于等离子体和颜色动力学的非线性,我们得到了Blazot { \it et. al.},物理修订信函72,3317(1994)中所述。类似地,通过忽略YM场的非线性和等离子体的非线性,它简化为Gupta { \it et. al.},Phys. Lett. B498,223(2005)。这样我们就得到了夸克-胶子等离子体(QGP)的最一般的非阿贝尔模。此外,我们的模型类似于激光束通过相对论等离子体的传播问题,Physica 9D,96(1983)。在没有非阿贝尔相互作用的情况下。

英文摘要:

We investigate fully nonlinear, non-Abelian excitations of quark-antiquark plasma, using relativistic fluid theory in cold plasma approximation. There are mainly three important nonlinearities, coming from various sources such as non-Abelian interactions of Yang-Mills (YM) fields, Wong's color dynamics and plasma nonlinearity, in our model. By neglecting nonlinearities due to plasma and color dynamics we get back the earlier results of Blaizot {\it et. al.}, Phys. Rev. Lett. 72, 3317 (1994). Similarly, by neglecting YM fields nonlinearity and plasma nonlinearity, it reduces to the model of Gupta {\it et. al.}, Phys. Lett. B498, 223 (2005). Thus we have the most general non-Abelian mode of quark-gluon plasma (QGP). Further, our model resembles the problem of propagation of laser beam through relativistic plasma, Physica 9D, 96 (1983). in the absence of all non-Abelian interactions.
