A Galilean non-renormalization theorem
I will consider a Galilean N=2 supersymmetric theory in 2+1 dimensions with F-term couplings, obtained by null reduction of a relativistic Wess-Zumino model. I will compute quantum corrections and check that, as for the relativistic parent theory, the F-term does not receive quantum corrections. Even more, I'll give evidence that the causal structure of the non-relativistic dynamics together with particle number conservation constrain the theory to be one-loop exact.
