Abstract The hadronization process of heavy hadrons with bottom and charm quarks, especially for baryons , in a dense QGP medium is largely not understood. We present within a coalescence plus fragmentation model the predictions for and spectra and the related baryon to meson ratios at RHIC and LHC. We will discuss how our model can predict values for / of the order of O(1), which is much larger than the expectations from fragmentation, and in agreement whit early data from STAR collaboration. Furthermore in the same scheme can be predicted a baryon to meson ratio / in pp collisions assuming that at the LHC top energies there can be the formation of QGP matter. The results show a considerable volume effects that significantly reduce the ratios, but still predict quite larger values with respect to fragmentation, in agreement with recent data from ALICE in pp collisions.
