摘要：
In a coalescence plus fragmentation approach we study the PT spectra of charmed hadrons D-0, D-s up to about 10 GeV and the Lambda(+)(c)/D-0 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 A(c)/D-0 is much flatter than the one for light baryon/meson ratio like phi- and Lambda/K.
