1 Erratum to: Eur. Phys. J. C (2020) 80:833 https://doi.org/10.1140/epjc/s10052-020-8381-0

This Erratum replaces incorrect plots shown in Fig. 7 with the corrected ones. In the publication, the NA57 [1] ratios of \({\** }{^-}\) and \(\overline{\** }{^+}\) to the number of wounded nucleons at \(\left<N_{W}\right> = 349\) by mistake were plotted at the wrong values. The ratios were calculated and plotted by mistake using \(\left<N_{W}\right> = 249.\)

The strangeness enhancement E at the mid-rapidity as a function of average number of wounded nucleons \(\left<N_{W}\right>\) calculated as a ratio of rapidity density for \({\** }{^-} \) production (left) and \(\overline{\** }{^+} \) production (right) in nucleus-nucleus interactions per \(\left<N_{W}\right>\) divided by the corresponding value for p+p interactions. Red circles – NA49 Pb+Pb at 158\(A\,\hbox {Ge}\hbox {V}\)  [2], blue squares – NA57 p+Be, p+Pb and Pb+Pb at the same center-of-mass energy \(\sqrt{s_{NN}}\) = 17.3 \(\hbox {Ge}\hbox {V}\)  [1], magenta triangles – STAR Au+Au at \(\sqrt{s_{NN}}\) = 200 \(\hbox {Ge}\hbox {V}\)  [3], gray diamonds – ALICE Pb+Pb at \(\sqrt{s_{NN}}\) = 2.76 \(\hbox {Te}\hbox {V}\)  [4]. The systematic errors are represented by shaded boxes

The correct normalization does not change the conclusions of the paper. The correctly normalized results are presented in Fig. 7.
