| * ABSTRACT | |||||||
| We propose a brane configuration for the (2+1)d, N=2 superconformal theories (CFT3) arising > from M2-branes probing toric Calabi-Yau 4-fold cones, using a T-duality transformation of M-theory. > We obtain intersections of M5-branes on a three-torus which form a 3d bipartite crystal lattice in a > way similar to the 2d dimer models for CFT4. The fundamental fields of the CFT3 are M2-brane > discs localized around the intersections, and the super-potential terms are identified with the atoms > of the crystal. The model correctly reproduces the complete BPS spectrum of mesons and baryons. |
