# Soft supersymmetry breaking of 4d $\mathcal{N}=2$ SCFT

## TL;DR

This paper classifies how to softly break four-dimensional $ ext{N}=2$ superconformal field theories (SCFTs) to generate a wide variety of new $ ext{N}=1$ and non-supersymmetric conformal field theories, leveraging known properties of the original theories.

## Contribution

It provides a systematic classification of soft supersymmetry breaking deformations for 4d $ ext{N}=2$ SCFTs, enabling the derivation of properties of resulting $ ext{N}=1$ SCFTs.

## Key findings

- Many new $ ext{N}=1$ SCFTs can be constructed from known $ ext{N}=2$ SCFTs.
- Properties like central charges and chiral spectra of new theories can be derived from parent theories.
- Seiberg duality relations can be established for the new $ ext{N}=1$ SCFTs.

## Abstract

A classification of soft SUSY breaking deformation of general four dimensional $\mathcal{N}=2$ SCFT is provided. Given the large class of newly discovered $\mathcal{N}=2$ SCFTs and their known properties such as the central charges and full information of BPS operators, it is possible to get a huge number of new $\mathcal{N}=1$ SCFTs and non-supersymmetric CFTs. Many properties of these new $\mathcal{N}=1$ SCFTs such as central charges, chiral spectrum and Seiberg duality can be derived from known information of parent $\mathcal{N}=2$ SCFT.
