Hydrodynamics is the accepted framework to describe the evolution of systems created in relativistic heavy-ion collisions. In smaller collision systems, such as proton-lead and proton-proton collisions, other, non-hydrodynamic explanations for the experimentally observed flow signals have been suggested. So which explanation is right or are they both? In this talk I review...

In this talk, I review the latest developments in high transverse momentum (pT) or mass probes of small heavy ion collision systems. These include measurements which utilize high-pT hadrons, fully reconstructed jets, photons and heavy electroweak bosons, and heavy flavor particles, as probes. I will discuss what these measurements can reveal about partonic structure and parton dynamics in...

While proton-proton collisions and heavy-ion collisions can be well-described by their own theoretical frameworks – factorization and hydrodynamics, respectively – the collisions of intermediate “small systems” pose unique challenges and opportunities. The “dilute-dilute” limit associated with proton-proton collisions is characterized by the dominance of a single partonic hard scattering...

Measurements of two-particle correlations in relative azimuthal angle and pesudorapidity have shown striking similarities between results obtained in pp, and in p+A and A+A collision systems. In pp collisions, unlike in the p+A and A+A systems, the strength of the correlations quantified by the anisotropy parameter $v_2$ does not show any dependence on the charged-particle multiplicity. Recent...
