This is my recent joint work with Nakao Hayashi and Chunha Li. We study the scattering theory for a system of Schr\"odinger equations with quadratic interactions.

We show how the gauge invariance of the interactions under the mass resonance condition has an influence on the large time asymptotics of solutions.
