Abelian gauge invariance of the WZ-type coupling in ABJM theory

Abstract

We construct the interaction terms between the worldvolume fields of multiple M2-branes and 3-form gauge field of 11-dimensional supergravity, in the context of ABJM theory. The obtained Wess-Zumino-type coupling is simultaneously invariant under the U-L(N) x U-R(N) non-Abelian gauge transformation of the ABJM theory and the Abelian gauge transformationof the 3-form field in 11-dimensional supergravity.
