| Popis: | The production cross section of prompt A(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 root sNN = 5.02 TeV. The A(c)(+) and (A) over bar (-)(c)baryons were reconstructed in the hadronic decay channels A(c)(+)-> pK(-)st+ and A(c)(+)-> pK(S)(0) and respective charge conjugates. The measured differential cross sections as a function of transverse momentum (pT) and the pT-integrated A+c production cross section in pp and in p-Pb collisions are presented. The A(c)(+) nuclear modification factor (R-pPb), calculated from the cross sections in pp and in p-Pb collisions, is presented and compared with the R-pPb of D mesons. The A+c /D0 ratio is also presented and compared with the light-flavor baryon-to-meson ratios p/st and A/KS0, and measurements from other LHC experiments. The results are compared to predictions from model calculations and Monte Carlo event generators. |
