Abstract

The photoproduction of J / ψ mesons at low transverse momentum is studied in peripheral lead-lead collisions collected by the LHCb Collaboration at a center-of-mass energy per nucleon pair of 5 TeV , corresponding to an integrated luminosity of 210 μ b − 1 . The J / ψ candidates are reconstructed through the prompt decay into two muons of opposite charge in the rapidity region of 2.0 < y < 4.5 . The results significantly improve previous measurements and are compared to the latest theoretical prediction.
