Energy-energy correlators(EECs) has recently emerged as an excellent jet substructure to study space-time information of parton shower. We explore the EECs within $\gamma$-jets using our LBT and CoLBT-hydro frameworks. We investigate the effects of jet quenching, medium-induced gluon radiation, and medium response on EECs in AA collisions compared to pp collisions. Additionally, we find that...
Jet substructure provides precise tests of Quantum Chromodynamics (QCD) and offers a distinct way to study hadronization mechanisms, compared to measurements of hadrons alone. 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 Casimir factors of quarks and gluons, as well as the parton mass,...
Energy-energy correlators and their three point counterpart have recently been of great interest to the heavy ion jet community as they directly provide the virtuality scale and are relatively simple to calculate. Recent measurements of the two point correlator in PbPb collisions compared to pp collisions by CMS show interesting trends, even when accounting for the energy loss causing a shift...
Quark gluon plasma (QGP), when viewed at length scales of order the inverse of its temperature, behaves as a strongly coupled liquid. However, when it is probed at shorter length scales or with sufficiently high momentum transfer, asymptotic freedom mandates the presence of quark-like and gluon-like quasi-particles. High energy partons within jets can trigger these high-momentum exchanges,...
The Large Hadron Collider beauty (LHCb) experiment allows for the exploration of jet substructure in novel ways. It is a fully instrumented spectrometer in the forward region, permitting increased sensitivity for heavy flavor hadron production as well as jets initiated by a light quark produced in association with a Z0 boson. This allows for an analysis of the mass and flavor dependence of jet...
We explore modification of jet properties in high-multiplicity proton-proton (pp) collisions at $\sqrt{s} = 13$ TeV, utilizing the PYTHIA 8 Monash 2013 Monte Carlo simulation. While the formation of a quark-gluon plasma (QGP) is typically associated with jet quenching, our investigation focuses on jet modifications arising purely from non-QGP mechanisms, including color reconnection (CR) and...
Collinear drop observables suppress energetic, collinear contributions and enhance the sensitivities to soft radiation where medium modifications are most significant. While the Lund plane contains comprehensive information about radiation, collinear drop observables can be concretely designed to probe specific regions of phase space which qualitative features of medium modifications may...
