Notes on Supersymmetry Enhancement of ABJM Theory

الأصل · EN

We study the supersymmetry enhancement of ABJM theory. Starting from a N=2 supersymmetric Chern-Simons matter theory with gauge group U(2)(2) which is a truncated version of the ABJM theory, we find by using the monopole operator that there is additional N=2 supersymmetry related to the gauge group. We show this additional supersymmetry can combine with N=6 supersymmetry of the original ABJM theory to an enhanced N=8 SUSY with gauge group U(2)(2) in the case k=1,2. We also discuss the supersymmetry enhancement of the ABJM theory with U(N)(N) gauge group and find a condition which should be satisfied by the monopole operator.
