Algebraic renormalization of parity-preserving QED(sub 3) coupled to scalar matter I: unbroken case

摘要

In this letter the algebraic renormalization method, which is independent of any kind of regularization scheme, is presented for the parity-preserving QED(sub 3) coupled to scalar matter in the symmetric regime, where the scalar assumes vanishing vacuum expectation value,<(phi)>=0. The model shows to be stable under radiative corrections and anomaly free. (author). 17 refs.; e- mail: oswaldo at cbpfsu1.cat.cbpf.br; franco at cbpfsu1.cat.cbpf.br; piguet at sc2a.unige.ch.
