## Abstract

Coincident M2 branes at a conical singularity are related to M theory on AdS_{4} × X_{7} for an appropriate 7 dimensional Sasaki-Einstein manifold X_{7}. For X_{7} = Q^{1,1,1} = (SU(2) × SU(2) × SU(2)/(U(1) × U(1)) which was found sometime ago, the infrared limit of the theory on N M2 branes was constructed recently. It is the SU(N) × SU(N) × SU(N) gauge theories with three series of chiral fields A_{i},i = 1,2 transforming in the (N,N̄,1) representation, B_{j},J = 1,2 transforming in the (1,N,N̄) representation and C_{k},k = 1,2 transforming in the (1,N,N̄) representation. From the scalar Laplacian of X_{7} on the supergravity side, we discuss the spectrum of chiral primary operators of dual script N sign = 2 superconformal field theory in 3 dimensions. We study M5 branes wrapped over 5-cycle of X_{7} which were identified as (three types of) baryon like operators made out of N chiral fields recently. We consider M5 brane wrapped over 3-cycle of X_{7} which plays the role of domain wall in AdS_{4}. The new aspect arises when baryon like operators (M5 branes wrapped over 5-cycle) cross a domain wall (M5 brane wrapped over 3-cycle), M2 brane between them must be created.
