Current quark mass and g-2 of muon and ee-->ππ

Abstract

Based on an effective chiral theory of mesons the dependences of $\rho -\omega$ mixing and the vertex $\omega \pi \pi$ on $m_d-m_u$ are found. The form factor of pion agrees with data in both space- and time-like regions. CVC is satisfied. The values of g-2 of muon from $\pi \pi$ channel are calculated in the range of $q^2<1.3^{2}Ge{V}^2$.
