Parallel session 14: Jets II
- Urs Wiedemann (CERN)
The sPHENIX experiment is a next-generation collider detector at RHIC designed for rare jet and heavy flavor probes of the Quark-Gluon Plasma. The experiment includes large-acceptance, hermetic electromagnetic (EMCal) and hadronic (HCal) calorimeter systems, along with a very high-rate data acquisition plus trigger system. In RHIC Run-24, sPHENIX sampled 107/pb of p+p collision data at 200 GeV...
The diffusion wake accompanying the jet-induced Mach cone provides a unique probe of the properties of quark-gluon plasma in high-energy heavy-ion collisions. It can be characterized by a depletion of soft hadrons in the opposite direction of the propagating jet. We explore the 3D structure of the diffusion wake induced by γ-triggered jets in Pb+Pb collisions at the LHC energy within the...
In the last years, it has become clearer that recoiling particles originated due to elastic scatterings between the energetic partons within a jet and the medium constituents within the QGP are of great importance for jet quenching phenomenology. Current implementations in state-of-the-art models consider that the elastic scattering process takes place between an on-shell energetic parton and...
The flavour dependence of parton showers presents a unique opportunity to explore fundamental properties of QCD interactions. In particular, the substructure of low-energy jets containing heavy-flavour hadrons provides experimental access to both mass effects as well as the impact of Casimir colour factors. Using novel tracing methods, splittings of charm quarks are isolated to measure...
Jet substructure provides precise tests of Quantum Chromodynamics (QCD) and offers more differential ways to study hadronization mechanisms, compared to measurements of single hadrons. QCD predicts that jet radiation patterns depend on the mass and color charge of the initiating parton. Parton showers, in particular, are sensitive to the different Casimir factors of quarks and gluons, as well...
