Does the Higgs mechanism favour electron-electron bound states in   Maxwell-Chern-Simons QED_3?
  The low-energy electron-electron scattering potential is derived and discussed for the Maxwell-Chern-Simons model coupled to QED_3 with spontaneous symmetry breaking. One shows that the Higgs mechanism might favour electron-electron bound states.
