In this talk, I will discuss how BCFW recursion relations can be used to compute all tree-level scattering amplitudes in terms of 2 → 2 scattering amplitude in U(N) N = 2 Chern-Simons (CS) theory coupled to matter in fundamental representation. It is interesting to note that, even though the non-supersymmetric Chern-Simons theory coupled to fundamental fermions or bosons does not admit a good BCFW deformation, we can use the N = 2 supersymmetric recursion relations to write down a recursion relation for a non-supersymmetric fermionic theory. I will discuss the utility of higher point amplitudes from the point of proving dualities in the Chern-Simons theories coupled to matter.
