Description
In this talk, we will show how $\eta \to 3 \pi$ is the golden channel for determining the light quark mass ratio from experiment. We will review the different extractions and uncertainty assessment. The results will be compared with lattice QCD determinations and the opportunities for further improvement will be discussed.
