The corrected distributions are plotted in figure 1and figure 2, respectively. The mistake affects only the absolute predicted cross section. The current cross section is in agreement with earlier calculation [2], which was done within the simplified model (‘HEF’ in [1]) and similar (but not exactly the same) kinematic cuts. The error does not affect any other distributions presented in the paper nor the conclusions. Open Access,c The Authors. Article funded by SCOAP3.https://doi.org/10.1007/JHEP02(2019)158

Differential cross section as a function of the azimuthal angle between the jets for p+p and p+Pb collisions (rescaled by the number of nucleons). The distributions are identical everywhere expect near ∆φ≃π, where saturation is the strongest. The plot replaces figure 4 left in [1]. – 2 –
