TL;DR
This paper presents recent measurements of charged-particle jets at STAR across different collision systems, providing insights into jet quenching, medium modification, and QCD phenomena in both vacuum and hot dense media.
Contribution
It offers new experimental data on jet properties and correlations in p+Au and Au+Au collisions, enhancing understanding of jet quenching and medium effects at RHIC energies.
Findings
High-$p_T$ jets inversely related to event activity in p+Au
No significant jet quenching observed in high-EA p+Au collisions
Jet suppression and broadening studied in Au+Au collisions
Abstract
Jets serve as an important tool to probe QCD both in the vacuum and in the hot and dense medium. The STAR experiment at RHIC plays a key role in studying QCD phenomena across different collision systems (+, +A, A+A), offering access to a kinematic regime that complements that of the LHC. Building on recent jet and event activity studies at STAR, we present recent measurements on charged-particle jets at GeV. In +Au collisions, we explore event activity (EA) measured in the Au-going direction and its correlation with particle production at mid-rapidity. While soft particle production increases with EA, high- jets are found to be inversely related to EA. Ratios of imbalance and azimuthal dijet separation between high- and low-EA events show no significant differences, suggesting no strong evidence of jet quenching…
