Measurement of J/ψ helicity distributions in inelastic photoproduction at HERA

Measurement of J/ψ helicity distributions in inelastic photoproduction at HERA

The J/ψ decay angular distributions have been measured in inelastic photo-production in ep collisions with the ZEUS detector at HERA, using an integrated luminosity of 468 pb-1. The range in photon-proton centre-of-mass energy, W, was 50 < W < 180 GeV. The J/ψ mesons were identified th...
