Supersymmetry anomalies, exotic pairs and the supersymmetric standard model

TL;DR

This paper explores potential supersymmetry anomalies linked to the large BRS cohomology in 3+1 dimensions, introduces the concept of exotic pairs, and discusses implications for the supersymmetric standard model.

Contribution

It advances understanding of SUSY anomalies by analyzing BRS cohomology and introduces the novel concept of exotic pairs within the supersymmetric standard model.

Findings

Large BRS cohomology suggests possible SUSY anomalies.

Exotic pairs are identified in the massless supersymmetric standard model.

Discussion of unresolved issues related to SUSY anomalies.

Abstract

For 34 years it has been known that chiral supersymmetry (SUSY) in 3+1 dimensions has a very large Becchi-Rouet-Stora (BRS) cohomology space at ghost charge one. This suggests that there might be corresponding SUSY anomalies coming from linearly divergent, triangle, Feynman diagrams. This paper discusses some progress and some outstanding issues related to these questions. The concept of exotic pairs is introduced, with an example from the massless supersymmetric standard model.
