Measurement of exclusive $${\varvec{{{{\pi ^+\pi ^-}}}}}$$ π + π - and $${\varvec{{{{\rho ^0}}}}}$$ ρ 0 meson photoproduction at HERA

Abstract Exclusive photoproduction of $${{\rho ^0}} (770)$$ ρ 0 ( 770 ) mesons is studied using the H1 detector at the ep collider HERA. A sample of about 900,000 events is used to measure single- and double-differential cross sections for the reaction $$\gamma p \rightarrow \pi ^{+}\pi ^{-}Y$$ γ p...
