4WJA.00002: Modification of hard and soft components of jets Invited Speaker: Yasuki Tachibana The jet is a multi-scale probe that can explore interactions in the quark-gluon plasma medium across a wide range of momentum scales. In the first part of the talk, we focus on the impact of scale-dependent jet-medium interactions on jet substructure observables, particularly during the high momentum and virtuality phase. Utilizing the JETSCAPE framework, we perform event-by-event Monte Carlo simulations with explicit virtuality dependence in the jet-medium interaction rate within the MATTER+LBT setup [1,2]. We emphasize jet substructure observables, such as Soft Drop groomed observables and the jet fragmentation function. Our results are compared to data and highlight the significant reduction in jet-medium interaction during the early high-virtuality stage. |

4WJA.00003: Unraveling the Hard Probe-Induced Medium Response with Jet Data Invited Speaker: YEN-JIE Lee We present physics analyses sensitive to the medium response induced by hard probes in heavy-ion collisions using jet and hadrons tagged with electroweak bosons. By studying the modifications observed in the underlying events and in these jets produced within the Quark-Gluon Plasma (QGP) compared to a vacuum, we aim to unravel the intricate interplay between energetic partons and the QGP constituents. |
