Low-energy electron-electron bound states in planar QED

In this talk, we present a parity-preserving QED3 model with spontaneous breaking of a local U(1)-symmetry. The breaking is accomplished by a potential of the ' 6 -type. It is shown that a net attractive interaction appears in the Moller scattering (s- and p-wave scatterings between two electrons) as mediated by the gauge field and a Higgs scalar. We show, �
