“…In order to introduce such WZ-type couplings as interaction terms in the M2-brane theory, the non-Abelian U(N) × U(N) gauge symmetry of the ABJM theory should be preserved by the interaction terms. In relation with this issue, there were several works in the literature [30,31,[33][34][35][36][37][38][39]. Specially in [31,35,[37][38][39], the gauge invariant WZ-type couplings were constructed under the assumption that the 3-form and 6-form gauge fields depend on scalar fields Y A , Y † A as well as worldvolume coordinates (t, w 1 , w 2 ) of the M2-branes.…”
