Dispersive analysis of $$\eta \rightarrow 3 \pi $$ η→3π
Abstract The dispersive analysis of the decay $$\eta \rightarrow 3\pi $$ η→3π is reviewed and thoroughly updated with the aim of determining the quark mass ratio $$Q^2=(m_s^2-m_{ud}^2)/(m_d^2-m_u^2)$$ Q2=(ms2-mud2)/(md2-mu2) . With the number of subtractions we are using, the effects generated by t...
