Diffractive photoproduction of two oppositely charged pions off protons is measured in the photon-proton energy range $20<W<80$ GeV and invariant dipion mass $0.4<m_{\\pi\\pi}<2.2$ GeV. The data were recorded in  electroproduction at $ep$ centre-of-mass energy $\\sqrt{s}=319$ GeV for momentum transfer $Q^2<2.5$ GeV$^2$. Results are given as photon-proton cross sections but can be converted to $ep$ cross sections using the tabulated effective photon flux. Both elastic ($m_Y=m_p$) and proton-dissociative ($1<m_Y<10$ GeV) reactions are measured. The  measurements are done single- and double-differential in the di-pion mass and the momentum transfer $t$, in bins of the photon-proton energy $W$. The mass spectra are fitted by a Soding-inspired model, such  that production cross sections of $\\rho^0(770)$ mesons are extracted differential in $t$ as a function of $W$, thus giving access to the Pomeron trajectory.","name":"Measurement of Exclusive $\\pi^{+}\\pi^{-}$ and $\\rho^0$ Meson Photoproduction at HERA","url":"https://www.hepdata.net/record/ins1798511?version=1"},"keywords":"22.5, 23, 27.5, 29, 32.5, 35, 37.5, 42, 42.5, 47.5, 51, 53, 61, 68, 73, 319.0, RHO, Photoproduction, Diffractive, Vector Meson, Single Differential Cross Section, Double Differential Distribution, E+ P --> E+ PI+ PI- P, GAMMA P --> PI+ PI- P, E+ P --> E+ PI+ PI- X, GAMMA P --> PI+ PI- X, E+ P --> E+ RHO P, GAMMA P --> RHO P, E+ P --> E+ RHO X, GAMMA P --> RHO X","name":"Table 18-19 statistical correlations","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/105657","version":1}
