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 predictions obtained with a coalescence plus fragmentation model, for spectra, the related baryon to meson ratios and the ratio, both at RHIC and LHC energies in a wide range of transverse momentum. We discuss how our model can naturally predict values of the order of O(1) for as recently measured at both RHIC and LHC. Moreover assuming that at the LHC top energies there can be the formation of QGP, we show that in the same scheme due to considerable volume effect a still large is predicted as seen by ALICE in pp collisions.
