摘要:

提出了一种具有扭曲N=4超对称性的三维超Yang-Mills模型的格点形式。利用修正的莱布尼兹规则,在格点上完全精确地实现了八个超荷的广义超对称代数。我们采用的公式是在我们以前提出的二维格点上的Dirac Kaehler扭曲N=2超Yang-Mills中发展的显规范协变方法的三维推广。扭曲的N=4超对称代数是几何实现的三维晶格与链接超荷和使用的“移动”(反)?一个可能的解决方案,最近的批评的联系制定将进行讨论。

英文摘要:

We propose a lattice formulation of three dimensional super Yang-Mills model with a twisted N=4 supersymmetry. The extended supersymmetry algebra of all the eight supercharges is fully and exactly realized on the lattice with a modified "Leibniz rule". The formulation we employ here is a three dimensional extension of manifestly gauge covariant method which was developed in our previous proposal of Dirac-Kaehler twisted N=2 super Yang-Mills on two dimensional lattice. The twisted N=4 supersymmetry algebra is geometrically realized on a three dimensional lattice with link supercharges and the use of "shifted" (anti-)commutators. A possible solution to the recent critiques on the link formulation will be discussed.
