Abstract
For three dimensional N = 6 superconformal field theories we compute one–loop scattering amplitudes for any number of external particles. We focus on a particular subsector of N = 2 invariant superamplitudes for which the ordinary pertur- bative evaluation becomes very easy. The result we obtain is in general non–vanishing. For six external particles our findings are sufficient for determining the complete ex- pression of the N = 6 superamplitude at this order. We discuss the symmetries of the result and its anomalous variation under superconformal generators
