The antiproton-nucleus ($\bar{p}A$) annihilation is one of the main processes in antimatter studies, as antiparticles are mostly detected through their annihilation. Despite its significance, the process itself is not well established and the lack of models for low energies complicates the simulation of detectors for the experiments conducted at CERN's Antiproton Decelerator.
