Abstract

In a coalescence plus fragmentation approach we study the pT spectra of charmed hadrons D⁰, D_s up to about 10 GeV and the Λ⁺_c /D⁰ ratio from RHIC to LHC energies. In this study we have included the contribution from decays of heavy hadron resonances and also that due to fragmentation of heavy quarks that are left in the system after coalescence. The p_T dependence of the heavy baryon/meson ratios is found to be sensitive to the heavy quark mass. In particular we found that the Λ_c/D⁰ is much flatter than the one for light baryon/meson ratio like p/π and Λ/K.
