Photoproduction of ${\pi }^{+}{\pi }^{-}$ meson pairs on the proton

M. Battaglieri, R. De Vita, A. P. Szczepaniak

The exclusive reaction $\gamma p\to p{\pi }^{+}{\pi }^{-}$ was studied in the photon energy range 3.0 - 3.8 GeV and momentum transfer range $0.4<-t<1.0$ GeV${}^2$. Data were collected with the CLAS d…
