Remarkable suppression of the $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}$ contribution error into muon $g-2$

E. Bartos, S. Dubnicka, A. -Z. Dubnickova +1

We use the unitary and analytic model of the pion electromagnetic form factor in order to evaluate in the lowest order the $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}$ contribution into the muon magn…
