Hadron lists based on experimental studies summarized by the Particle Data Group (PDG) are a crucial input for equation of state and thermal models used in study strongly-interacting matter produced heavy-ion collisions. Modeling these systems is carried out via hydrodynamical simulations, which followed hadronic transport codes that also require list as input. To remain consistent throughout different stages modeling collision, same hadron with its corresponding decays must be at each step. It has been shown even most uncertain states listed PDG from 2016 required to reproduce partial pressures susceptibilities Lattice Quantum Chromodynamics known PDG2016+. Here, we update use collision including latest information all Booklet 2021. We then compare our new list, called PDG2021+, results find it achieves better agreement first principles calculations than PDG2016+ list. Furthermore, develop novel scheme intermediate decay channels allows only binary decays, such PDG2021+ will compatible framework SMASH. Finally, make comparisons data discuss impact particle yields spectra.
