In this talk, I discuss new perspectives on hadronization — the process by which quarks and gluons confine into color-neutral bound states. Hadronization is essential for collider physics, since the particles we detect are most often hadrons. Despite its importance, a first-principles description remains elusive. I will show how methods from quantum information theory can be used to constrain hadronization models employed in general-purpose Monte Carlo generators. Finally, I will motivate specific experimental measurements that could deepen our understanding of hadronization.
