U(2)-chiral symmetries of supersymmetric QED3

Abstract

Supersymmetry is studied in 2+1 dimensions. In addition to the multiplets corresponding to those in 3+1 dimensions the Clifford algebra allows an extra set. When the extra chiral multiplet is included, formulating supersymmetric QED3 in the manner of Wess and Zumino yields a lagrangian with a richer 'chiral' symmetry than that derived from supersymmetric QED by dimensional reduction.

arXiv commentPaper withdrawn. The `P'-multiplets are really just another way of writing the ordinary multiplet with a gamma_{45} in front of the fermions and negative signs in front of some of the bosons
