In this letter the algebraic renormalization method, which is independent of any kind of regularization scheme, is presented for the parity-preserving QED 3 coupled to scalar matter in the symmetric regime, where the scalar assumes vanishing vacuum expectation value, ϕ =0. The model shows to be stable under radiative corrections and anomaly free.The study of gauge field theories in 3 space-time dimensions [1] has been well-supported by a possible field-theoretical approach to describe some Condensed Matter phenomena, such as High-T c Superconductivity and Quantum Hall Effect [2,3]. Some Abelian models have been proposed in this direction, namely, the QED 3 and τ 3 QED 3 [4,5].One of the interesting properties of 3-dimensional gauge field theories is the Landau gauge finiteness of non-Abelian Chern-Simons theories [6].The confinement of massive electrons in 3 space-time dimensions is a remarkable characteristic of this lower dimensional space [7]. Recently, it was shown by using the Bethe-Salpeter equations that in a parity-preserving QED 3 there are bound states in electron-positron systems, positronium states [8].In a recent work [9], a parity-preserving QED 3 with spontaneous breaking of a local U(1)-symmetry was proposed. The breakingdown is accomplished by a sixth-power potential. It was shown that electrons scattered in D=1+2 can experience a mutual attractive interaction, depending on their spin states, where the intermediate bosons involved in *
