Determination of the quark mass ratio $Q$ from $η \to 3 π$

Stefan Lanz

The decay $η \to 3 π$ proceeds exclusively through isospin violating operators and is therefore an excellent probe to examine the strength of isospin breaking in the strong interact…

Dispersive analysis of $η \to 3 π$

Gilberto Colangelo, Stefan Lanz, Heinrich Leutwyler +1

The dispersive analysis of the decay $η \to 3 π$ is reviewed and thoroughly updated with the aim of determining the quark mass ratio ~ $Q^{2} = (m_{s}^{2} - m_{u d}^{2}) / (m_{d}^{2} - m_{u}^{2})$ . With the nu…
