Hadronization via coalescence at RHIC and LHC

An hadronization model that includes coalescence and fragmentation is used in this work to obtain predictions at both RHIC and LHC energy for light and strange hadrons transverse momentum spectra (π , p , k , Λ) and baryon to meson ratios (p /π , Λ/k ) in a wide range of pT . This is accomplished without changing coalescence parameters. The ratios p /π and Λ/K shows the right behaviour except for some lack of baryon yield in a limited pT range around 6 GeV. This would indicate that the AKK fragmentation functions is too flat at pT < 8 GeV
