Exact results for Wilson loops in orbifold ABJM theory 后印本

摘要: We investigate the exact results for circular 1/4 and 1/2 BPS Wilson loops in the d = 3 N = 4super Chern-Simons-matter theory that could be obtained by orbifolding Aharony-Bergman-Jafferis-Maldacena (ABJM) theory. In literature there is the partition function of the N= 4 orbifold ABJM theory, and in this paper we re-derive it in a slightly different method. We calculate the vacuum expectation values of the circular 1/4 BPS Wilson loops in fundamental representation and circular 1/2 BPS Wilson loops in arbitrary representations. We use both the saddle point approach and Fermi gas approach. The results for Wilson loops are in accord with the available gravity ones.
