Sažetak
The production cross section of prompt +c charm baryons was measured with the ALICE detector at the LHC at midrapidity in proton-proton (pp) and proton- lead (p–Pb) collisions at a center-of-mass energy per nucleon pair of √sNN = 5.02 TeV. The +c and −c baryons were reconstructed in the hadronic decay channels +c → pK−π+ and + c → pK0S and respective charge conjugates. The measured differential cross sections as a function of transverse momentum (pT ) and the pT -integrated +c production cross section in pp and in p–Pb collisions are presented. The +c nuclear modification factor (RpPb), calculated from the cross sections in pp and in p–Pb collisions, is presented and compared with the RpPb of D mesons. The +c/D0 ratio is also presented and compared with the light-flavor baryon-to-meson ratios p/π and /K0S, and measurements from other LHC experiments. The results are compared to predictions from model calculations and Monte Carlo event generators.
