Does the Higgs mechanism favour electron-electron bound states in Maxwell-Chern-Simons QED_3?
H. Belich, O. M. Del Cima, M. M. Ferreira +1
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 tha…

Low-energy electron-electron bound states in planar QED
H. R. Christiansen, O. M. Del Cima, M. M. Ferreira +1
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 phi^6-type. It is sho…

Comment on ``On spin-1 massive particles coupled to a Chern-Simons field''
O. M. Del Cima, D. H. T. Franco, J. A. Helayel-Neto +1
In this comment we discuss some serious inconsistencies presented by Gomes, Malacarne and da Silva in their paper, Phys.Rev. D60 (1999) 125016 (hep-th/9908181).
