Experimental results on p(d)+Ap(d)+A collisions at RHIC and the LHC

Recent experimental results at both the LHC and RHIC show evidence for hydrodynamic behavior in proton–nucleus and deuteron–nucleus collisions (p+Ap+A). This unexpected finding has prompted new measurements in p+Ap+A collisions in order to understand whether matter with similar properties is created in A + A and p+Ap+A collisions or whether another explanation is needed. In this proceedings, we will discuss the new experimental data and its interpretation within the context of heavy-ion collisions.
