## Abstract

We introduce an N = 1 supersymmetric generalization of the mechanical system describing a particle with fractional spin in D=1+2 dimensions and being classically equivalent to the formulation based on the Dirac monopole two-form. The model introduced possesses hidden invariance under the

N=2 Poincaré supergroup with a central charge saturating the BPS

bound. At the classical level the model admits a Hamiltonian formulation with two first class constraints on the phase space T∗(R

^{1,2})×L^{1|1}. Where the Kähler supermanifold L^{1|1}≅OSp(2∣2)/U(1∣1) is a minimal superextension of the Lobachevsky plane. The model is quantized by combining the geometric quantization on L^{1|1}and the Dirac quantization with respect to the first class constraints. The constructed quantum theory describes a supersymmetric doublet of fractional spin particles. The space of quantum superparticle states with a fixed momentum is embedded into the Fock space of a deformed bosonic oscillator.Original language | English |
