Current quark mass and g-2 of muon and ee-->ππ
Abstract
Based on an effective chiral theory of mesons the dependences of $ρ-ω$ mixing and the vertex $ωππ$ 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 $ππ$ channel are calculated in the range of $q^2<1.3^2 GeV^2$.
