Description
co-host: Matt Sievert
High energy heavy ion collisions enable the production of a state of strongly interacting deconfined nuclear matter called the Quark Gluon Plasma (QGP). Jets are a powerful probe of this nuclear medium as the partons inside the jet are expected to lose energy as they interact with the medium causing the phenomenon known as jet quenching. Through studying a variety of jet properties at both the...
Whether quark- and gluon-initiated jets are modified differently by the quark-gluon plasma produced in heavy-ion collisions is a long-standing question that has thus far eluded a definitive experimental answer. A crucial complication for quark-gluon discrimination in both proton-proton and heavy-ion collisions is that all measurements necessarily average over the (unknown) quark-gluon...
Jet substructure, defined by observables constructed from the distribution of constituents within a jet, provides the versatility to tailor observables to specific regions of QCD radiation phase space. This flexibility allows us to test not only our understanding of perturbative QCD but also the nature of nonperturbative effects including hadronization — and has resulted in jet substructure...
In this talk we will outline the connections among the inclusive jet correlator, the single-hadron fragmentation correlator, and the quark propagator, which open the way to studies of fundamental mechanisms in QCD -such as the dynamical generation of mass- by looking at the fully inclusive hadronization of a quark. In particular, we will focus on observables in semi-inclusive DIS and $e^+e^-$...
The sPHENIX detector at the BNL Relativistic Heavy Ion Collider (RHIC) benefits from the extensive advances of the Large Hadron Collider (LHC) and Electron-Ion Collider (EIC) detector R&D. The combination of electromagnetic calorimetry, hermetic hadronic calorimetry, precision tracking, and the ability to record data at high rates without trigger bias enables pioneering measurements of jets,...
