Sirunyan, A. M.; Işıldak, Bora (Springer Nature, 2020-05-18)This erratum corrects the dedication in the PDF version of the original published manuscript: diractive processes should be diffractive processes. Abstract: Events with no charged particles produced between the two leading ... -
Erratum: Measurement of prompt and nonprompt charmonium suppression in PbPb collisions at 5.02 TeV
Sirunyan, A. M.; Işıldak, Bora (Springer, 2023-02)In Fig. 3, the y axis titles were mistakenly written showing a single-differential cross section in either dimuon (Formula presented.) or rapidity, when in fact the cross section is normalized by both the (Formula presented.) ... -
