We analyze the 3d free massive fermion theory coupled to external sources. The presence of a mass explicitly breaks parity invariance. calculate two- and three-point functions gauge current energy momentum tensor and, for instance, obtain well-known result that in IR limit (but also UV one) we reconstruct relevant CS action. then couple model higher spin currents work out 3 case. In an effective action which was proposed many years ago as possible generalization derive different This analysis can evidently be generalized spins. discuss conservation properties correlators intermediate steps our derivation.
