Abstract |
We present an N=2-supersymmetric extension [1] of Jackiw-Pi´s chiral gauge theory (CGT) [2] originally
designed to describe Dirac electrons in graphene. The augmented framework allows for the identification
of non-perturbative solutions, as vortex-like configurations that saturate a topologically non-trivial (BPS-
)bound are proven to be. Remarkably, that regime reveals to be free from extra scalar degrees of freedom
brought about to the model as needed partners to fermions in such a linear realisation of supersymmetry,
but lacking a phenomenological interpretation. Furthermore, inherent R-Parity provides the room for
incorporating a global phase-fermion number symmetry already manifest in the CGT, but now regarded as
an external (superspace) invariance. Comments on the fermionic mass-matrix and perspectives shall
compose our conclusions.
