## TL;DR

This paper reviews experimental analyses of isospin violations at BESIII, focusing on processes involving scalar mesons, baryon final states, and charmonium transitions, leveraging large datasets from the BEPCII collider.

## Contribution

It provides a comprehensive review of recent experimental studies on isospin violations at BESIII, highlighting new insights into light hadron spectra and charmonium decays.

## Key findings

- Observation of isospin violating processes with $f_0(980)$ and $a_0(980)$ production
- Evidence of isospin violation in baryon final states
- Analysis of isospin violating hadronic transitions in charmonium

## Abstract

At present very large data samples in the energy region of 2.0-4.6 GeV were accumulated by the BESIII detector, which is operated in the upgraded Beijing electron positron collider (BEPCII). These data samples provide an unprecedented opportunity in the study of light hadron spectra and charmonium(-like) decays. We review some experimental analyses related to isospin violations at BESIII in this proceeding, which can be classify into three categories: isospin violating processes with a $f_0(980)$ or $a^0_0(980)$ production, isospin violating processes with baryon final states, and isospin violating hadronic transitions in the charmonium system.
