M.L. Walker, C.J. Burden
TL;DR
This paper explores the enhanced chiral symmetries in supersymmetric QED3 due to additional multiplets permitted by the Clifford algebra, revealing richer symmetry structures in 2+1 dimensions.
Contribution
It introduces a formulation of supersymmetric QED3 that incorporates extra chiral multiplets, leading to a richer symmetry structure than traditional dimensional reduction approaches.
Findings
Identification of extra chiral multiplets in 2+1D supersymmetry
Demonstration of enhanced 'U(2)' chiral symmetry in QED3
Comparison with symmetries from 3+1D supersymmetry
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.
