Progress in hard probes of small collision systems
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 heavy nuclei, and how they relate to evidence for a possible formations of quark-gluon plasma, at RHIC and the LHC. I will also give some thoughts on future prospects with lighter collision species such as Ar+Ar or O+O at the LHC and opportunities with the sPHENIX detector at RHIC.
