Erratum to: Measurement of differential cross sections for single diffractive dissociation in $$ \sqrt{s} $$ = 8 TeV pp collisions using the ATLAS ALFA spectrometer

Figure 5b of the paper [1] contained a misinterpretation in the comparison between the reported new ATLAS measurement of the process pp → Xp and previously published CMS data [2]. The ATLAS measurement corresponds to cases where either proton dissociates.
