论文摘要
考虑了半结合的碰撞热QCD培养基（夸克 - 杜伦等离子体）中传播的表面波。为了研究碰撞作为阻尼和非理想因素的影响，在Bhatnagar-gross-krook（BGK）方法中使用了夸克 - 杜伦等离子体的纵向和横向介电功能。在长波长限制下，在分析和数值上获得了结果。首先，碰撞导致表面波频率的较小值及其更强的阻尼值。其次，结果表明，与无碰撞情况相比，非理想性导致表面波的新分支的出现。讨论了在实验中实现的QGP的表面激发（WAV）的相关性。
Surface waves propagating in the semi-bounded collisional hot QCD medium (quark-gluon plasma) are considered. To investigate the effect of collisions as damping and non-ideality factor, the longitudinal and transverse dielectric functions of the quark-gluon plasma are used within the Bhatnagar-Gross-Krook (BGK) approach. The results were obtained both analytically and numerically in the long wavelength limit. First of all, collisions lead to smaller values of surface wave frequency and their stronger damping. Secondly, the results show that non-ideality leads to the appearance of a new branch of surface waves compared to the collisionless case. The relevance of the surface excitations (waves) for the QGP realized in experiments is discussed.
