Lambda^+_c$ Production and Baryon-to-Meson Ratios in pp and p-Pb Collisions at $\sqrt {s_{NN}}$=5.02  TeV at the LHC

The prompt production of the charm baryon Λ c+ and the Λ c+ / D0 production ratios were measured at midrapidity with the ALICE detector in pp and p -Pb collisions at sNN=5.02  TeV . These new measurements show a clear decrease of the Λ c+ / D0 ratio with increasing transverse momentum ( pT ) in both...

Summary:The prompt production of the charm baryon Λ c+ and the Λ c+ / D0 production ratios were measured at midrapidity with the ALICE detector in pp and p -Pb collisions at sNN=5.02  TeV . These new measurements show a clear decrease of the Λ c+ / D0 ratio with increasing transverse momentum ( pT ) in both collision systems in the range 2
