Erratum to: Measurement of the Λc+ to D0 production ratio in peripheral PbPb collisions at sNN = 5.02 TeV(Journal Of High Energy Physics, (2023), 6, 10.1007/JHEP06(2023)132)

Lesya Shchutska, Olivier Schneider, Aurelio Bay, Guido Haefeli, Frédéric Blanc, Tatsuya Nakada, Michel De Cian, Elena Graverini, Renato Quagliani, Veronica Sølund Kirsebom

We report on a measurement of the Λ+c to D0 production ratio in peripheral PbPb collisions at √ sNN = 5.02TeV with the LHCb detector in the forward rapidity region 2 < y < 4.5. The Λ+c (D0) hadrons are reconstructed via the decay channel Λ+c → pK−π+ (D0 → ...
