Quantizing the (0,4) Supersymmetric ADHM Sigma Model

TL;DR

This paper investigates the quantization process of the (0,4) supersymmetric ADHM sigma model, focusing on anomaly contributions and the behavior as instanton size approaches zero.

Contribution

It provides a detailed analysis of quantum effects in the ADHM sigma model, highlighting anomaly contributions and the instanton size limit.

Findings

Quantum contributions are solely from chiral anomalies.

Computed first and second order anomaly terms.

Discussed the model's behavior in the zero-instanton-size limit.

Abstract

We discuss the quantization of the ADHM sigma model. We show that the only quantum contributions to the effective theory come from the chiral anomalies and compute the first and second order terms. Finally the limit of vanishing instanton size is discussed.
