Nuclear collisions allow the study of the Quark Gluon Plasma - a medium of deconfined quarks and gluons. At particle colliders, its presence is signaled by modifications of the measured particle spectra. The recent discovery of anisotropically distributed particles („collective flow“) in smaller collision systems while modifications to high-momentum spectra are absent is puzzling since both are associated with the presence of the QCD medium. In this work, no-medium baseline predictions for high-momentum observables are presented and theoretical limits to observing medium effects are discussed.
