The production of prompt Λ+c baryons at midrapidity (|y| < 0.5) was measured in central (0–10%) and mid-central (30–50%) Pb–Pb collisions at the center-of-mass energy per nucleon–nucleon pair √sNN = 5.02 TeV with the ALICE detector. The results are more precise, more differential in centrality, and reach much lower transverse momentum (pT = 1 GeV/c) with respect to previous measurements performed by the ALICE, STAR, and CMS Collaborations in nucleus–nucleus collisions, allowing for an extrapolation down to pT = 0. The pT-differential Λ+c /D0 ratio is enhanced with respect to the pp measurement for 4 < pT < 8 GeV/c by 3.7 standard deviations (σ ), while the pT-integrated ratios are compatible within 1σ.The observed trend is similar to that observed in the strange sector for the /K0S ratio. Model calculations including coalescence or statistical hadronization for charm-hadron formation are compared with the data.

Neutron-skin effect in direct-photon and charged-hadron production in Pb+Pb collisions at the LHC
Helenius, Ilkka; Paukkunen, Hannu; Eskola, Kari (Springer, 2017)A well-established observation in nuclear physics is that in neutron-rich spherical nuclei the distribution of neutrons extends farther than the distribution of protons. In this work, we scrutinize the influence of this ... -
Production of muons from heavy-flavour hadron decays in pp collisions at √s = 5.02 TeV
ALICE Collaboration (Springer, 2019)Production cross sections of muons from semi-leptonic decays of charm and beauty hadrons were measured at forward rapidity (2.5 < y < 4) in proton-proton (pp) collisions at a centre-of-mass energy √s = 5.02 TeV with the ... -
Measurement of the production of high-pT electrons from heavy-flavour hadron decays in Pb–Pb collisions at √sNN = 2.76 TeV
ALICE Collaboration (Elsevier B.V., 2017)Electrons from heavy-flavour hadron decays (charm and beauty) were measured with the ALICE detector in Pb–Pb collisions at a centre-of-mass of energy √sNN = 2.76 TeV. The transverse momentum (pT) differential production ... -
Multiplicity dependence of light-flavor hadron production in pp collisions at √s = 7 TeV
ALICE Collaboration (American Physical Society, 2019)Comprehensive results on the production of unidentified charged particles, π±, K±, K0S, K∗(892)0, p, ¯p, ϕ(1020), Λ, ¯¯¯Λ, Ξ−, ¯¯¯Ξ+, Ω−, and ¯¯¯Ω+ hadrons in proton-proton (pp) collisions at √s=7 TeV at midrapidity (|y|<0.5) ... -
Production of muons from heavy-flavour hadron decays in p–Pb collisions at √sNN = 5.02 TeV
ALICE Collaboration (Elsevier BV, 2017)The production of muons from heavy-flavour hadron decays in p–Pb collisions at √sNN = 5.02 TeV was studied for 2 < pT < 16 GeV/c with the ALICE detector at the CERN LHC. The measurement was performed at forward (p-going ...
