Massless Wess-Zumino model as first quantized Siegel superparticle

TL;DR

This paper demonstrates that the canonical quantization of the 4D Siegel superparticle results in the massless Wess-Zumino model, with quantum states represented by real scalar superfields decomposing into chiral and antichiral components.

Contribution

It shows that the massless Wess-Zumino model naturally emerges from the quantization of the 4D Siegel superparticle, providing a link between superparticle quantization and supersymmetric field theories.

Findings

Quantum states are realized as real scalar superfields.

Superfields decompose into on-shell chiral and antichiral superfields.

The effective field theory corresponds to the massless Wess-Zumino model.

Abstract

It is shown that canonical quantization of the $4d$ Siegel superparticle yields massless Wess-Zumino model as an effective field theory. Quantum states of the superparticle are realized in terms of the real scalar superfields which prove to be decomposed into the sum of on-shell chiral and antichiral superfields.
