标题： A New Dimensionally Reduced Effective Action for QCD at High Temperature

摘要： 为纯规范SU(N)在高温下的静态模式的三维有效作用量推导出新的术语。 在以前的工作中，通过计算涉及2、3或4个外部静态胶子和一个内部非静态环的图，得到了有效顶点。 我采用了一种略有不同的方法，通过对静态模式的一环有效作用量进行协变导数展开，保留所有涉及最多六个协变导数的项。 得到的有效作用量在空间依赖的规范变换下明显保持不变，并包含新的五点和六点有效顶点。 显示英文摘要

摘要： New terms are derived for the three-dimensional effective action of the static modes of pure gauge SU(N) at high temperature. In previous works, effective vertices have been obtained by evaluating diagrams involving 2, 3 or 4 external static gluons with one internal nonstatic loop. I take a somewhat different approach by making a covariant derivative expansion of the one loop effective action for the static modes, keeping all terms involving up to six covariant derivatives. The resulting effective action is manifestly invariant under spatially dependent gauge transformations and contains new 5- and 6-point effective vertices.
