Measurement of the cross-section ratio σ ψ(2S) /σ J/ψ(1S) in exclusive photoproduction at HERA

Measurement of the cross-section ratio σ ψ(2S) /σ J/ψ(1S) in exclusive photoproduction at HERA

Abstract The exclusive photoproduction reactions γp → J/ψ(1S)p and γp → ψ(2S)p have been measured at an ep centre-of-mass energy of 318 GeV with the ZEUS detector at HERA using an integrated luminosity of 373 pb −1. The measurement was made in the kinematic range 30 < W < 180 GeV, Q 2 < 1 G...
