4. Electron–electron bound states in parity-preserving QED<SUB>3</SUB>

Author

Jr, H Belich, Cima, O M Del, Jr, M M Ferreira, and Helayël-Neto, J A

Abstract

By considering the Higgs mechanism in the framework of a parity-preserving planar quantum electrodynamics, one shows that an attractive electron–electron interaction may come out. The e− − e− interaction potential emerges as the non-relativistic limit of the Möller scattering amplitude and it may be made attractive with a suitable choice of parameters. Numerical values of the e− − e− binding energy are obtained by solving the two-dimensional Schrödinger equation. The existence of bound states is to be viewed as indicative that this model may be adopted to address the pairing mechanism in some systems endowed with parity preservation.

5. An Algebraic Proof on the Finiteness of Yang–Mills–Chern–Simons Theory in D=3

Author

Del Cima, O., Franco, D., Helayël-Neto, J., and Piguet, O.

Abstract

A rigorous algebraic proof of the full finiteness in all orders of perturbation theory is given for the Yang–Mills–Chern–Simons theory in a general three-dimensional Riemannian manifold. We show the validity of a trace identity, playing the role of a local form of the Callan–Symanzik equation, in all loop orders, which yields the vanishing of the β-functions associated to the topological mass and gauge coupling constant as well as the anomalous dimensions of the fields.
