Measurement of the $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}{\pi }^0{\pi }^0$ cross section using initial-state radiation at BaBar

The BaBar Collaboration

The process $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}2{\pi }^0\gamma$ is investigated by means of the initial-state radiation technique, where a photon is emitted from the incoming electron or positron. Using $454…
