What follows is a brief description of the nature of the problems, before the corrected results are given. The charge collected in the LHCb VELO sensors is affected by radiation damage. One such effect, which is more pronounced in the outer regions of downstream sensors, arises from charge induction on second metal layer routing lines [2]. Prior to the start of Run 2, modifications were made to the digitization step in the LHCb simulation framework to model this effect. An error was made in the parametric implementation resulting in a reduction of the track reconstruction efficiency in simulation compared to data for tracks with low pseudorapidity. The tracking efficiency calibration procedure that was applied in this paper to the data and simulation [3] was unable to correct the mismodelling. All results presented in the paper are affected and a similar pattern is seen for all four different mesons. The corrected cross-sections are generally lower with the largest difference at low rapidities and almost no change at high rapidities.
