Quantum dynamics of N=1, D=4 supergravity chiral compensator

TL;DR

This paper introduces a new superfield model for four-dimensional N=1 supergravity, analyzes its renormalization properties, and finds it is infrared free, contributing to understanding quantum effects in supergravity theories.

Contribution

The paper proposes a novel superfield model induced by supertrace anomaly and investigates its renormalization structure and infrared behavior.

Findings

The model is induced by supertrace anomaly in curved superspace.

One-loop counterterms are explicitly calculated.

The theory is shown to be infrared free.

Abstract

A new four-dimensional $N=1$ superfield model is suggested. The model is induced by supertrace anomaly of matter superfields in curved superspace and leads to effective theory of supergravity chiral compensator. A renormalization structure of this model is studied, one-loop counterterms are calculated and renormalization group equations are investigated. It is shown that the theory under consideration is infrared free.
