Jets produced in collisions of heavy nuclei lose energy as they pass through the hot, dense nuclear medium known as the quark-gluon plasma produced in the collision. The azimuthal anisotropy of jet production in heavy ion collisions measures the correlations of jets and the initial geometry of the collision, giving insight into path-length dependent energy loss in the medium. This talk will...

The sPHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) is designed to study the properties of the Quark-Gluon Plasma (QGP) using high-energy jets as calibrated hard probes. With high-resolution calorimetry and tracking, sPHENIX enables precision measurements of jet substructure observables that are sensitive to medium-induced modifications of parton showers. Jet substructure...

The study of jets and jet fragmentation plays a large role in understanding parton evolution within the Quark-Gluon Plasma (QGP). In QCD emissions from jets, photons can fragment from quarks, but these fragmentation photons have not been thoroughly investigated in the context of Heavy-ion Collisions. They could offer insight for investigating jet energy loss mechanisms in the QGP medium. This...

Jet transport coefficients computed in Hard-Thermal-Loop (HTL) effective theory are applicable at high temperature, while the medium created in heavy-ion collisions, at RHIC and LHC, predominantly samples the region near the QCD transition temperature. The dimensionless transport coefficient $\hat{q}/T^3$, calculated in leading order HTL theory, shows a monotonic rise with decreasing...

p+Au collisions at \sqrt{s}=200 GeV and discuss their implications for
QCD dynamics in small collision systems. These results probe the
possible roles of multi-parton interactions, long-range partonic correlations, and novel final-state effects in asymmetric p+Au

Measurements of heavy flavor quark correlations in heavy-ion collisions are crucial to understand the flavor dependence of quark energy loss mechanisms in hot and dense QCD matter. In addition to the heavy-ion collisions, experimental measurements of heavy flavor correlations in $p+p$ collisions can provide insights into the contributions of perturbative and non-perturbative QCD processes to...

The energy-energy correlator (EEC) inside jets is a sensitive observable for studying jet modification in the quark-gluon plasma (QGP). we employ an updated CoLBT-hydro framework in which a medium scale QM = 2.0 GeV is introduced to separate the vacuum and in-medium stages of the parton shower, enabling a more self-consistent treatment of jet evolution. Using a theoretical background...

Energy-Energy Correlator (EEC) applications to Heavy-Ion Collisions have been the subject of copious studies in recent years, namely in the exploration of the Quark-Gluon Plasma (QGP). EECs have been originally proposed to display a clear-cut scale factorization between different QCD processes, such as perturbative and non-perturbative effects, making them particularly appealing for...

Energy-Energy Correlators (EEC) probe the dynamics of the quark gluon plasma (QGP) by mapping the final-state energy by mapping the angular distribution of final-state energy. At the Relativistic Heavy Ion Collider (RHIC), $\sqrt{s_{NN}} = 200$ GeV collisions provide a complementary kinematic regime to the LHC, but jet substructure measurements are challenged by lower jet energies and a large...

Correlation functions of the asymptotic energy and charge flux connect the macroscopic structure of collider events to the underlying microscopic dynamics of the Standard Model. This talk presents measurements of the track energy-energy correlator and the one-point charge correlator in DELPHI Open Data in e+e- collisions. The measured energy-energy correlator is compared to record-precision...

We present a novel measurement of in-jet azimuthal asymmetry at $\sqrt{s}=91.2\,\mathrm{GeV}$ in $e^+e^-$ collisions, providing a precision vacuum reference and a controlled bridge to possible QGP-like collectivity in heavy-ion collisions. Using archived ALEPH data and validated simulations, we extract fully unfolded, per-jet constituent Fourier harmonics $V_n$ $(n=1\text{-}3)$ with respect to...

We present the first results from the JETSCAPE multi-stage event generator framework for electron-ion collisions. The use of calibrated modules from the JETSCAPE framework allows common model parameters to remain unchanged between p-A and e-A simulations, thereby introducing novel constraints on these extensive simulations. The e-A event generator within the JETSCAPE framework simulates an...

We combine the tools of global event shapes and jet electric charge into a unified factorization framework to probe quark flavor dynamics in the nucleon and the hadronization process. As a concrete example, we study jet charge measurements with the 1-Jettiness global event shape for Deep Inelastic Scattering (DIS) as a quark flavor probe of unpolarized or polarized parton distribution...

Target fragmentation provides a unique window into the correlation between the struck parton and the remnant system in semi-inclusive deep-inelastic scattering. While current and past studies of nucleon structure have largely focused on current fragmentation observables, the Electron-Ion Collider will enable precision measurements in the target-fragmentation region through its high luminosity,...

Oxygen–Oxygen collisions have recently opened a new avenue for studying the system-size dependence of QCD matter in relativistic nuclear collisions. Positioned between small systems such as pp and pA and large heavy-ion systems such as AuAu and PbPb, OO collisions provide a unique opportunity to investigate how collective phenomena and medium effects evolve with the size and density of the...

Systematic comparisons between experimental measurements and theoretical models are essential for validating and improving event generators, as well as stringent tests of the underlying physics and its implementation. The RIVET framework enables these studies through standardized and reproducible analysis routines that are directly aligned with published experimental results. We present a...
