1. Jets modification and medium response

Oral presentation

Jet substructure is a powerful tool for performing fundamental QCD tests in elementary particle collisions and offers unique insight into the microscopic structure of the QGP in heavy-ion collisions. Defined as the energy-weighted cross section of particle pairs inside jets, the two-point energy-energy correlator (EEC) is a novel jet substructure observable probing the correlation of energy...

1. Jets modification and medium response

Oral presentation

Energy-energy correlator has the advantage of isolating physics of different angular scales, which has attracted a lot of interest recently to study it in heavy-ion environments. Any modification from proton-proton reference can reveal hints about the inner workings of the quark-gluon plasma. In this presentation we will present the first measurement of the energy-energy correlator of jets in...

1. Jets modification and medium response

Oral presentation

Energy-energy correlators (EECs) have manifested an important probe to unveil the properties of QCD splitting in vacuum, which should be modified in the nuclear medium such as the quark-gluon plasma. By employing the recently developed multi-stage jet evolution framework JETSCAPE, we have investigated the nuclear modification of EECs of inclusive jets in heavy-ion collisions. We find EECs are...

108. Probing the Short-Distance Structure of the Quark-Gluon Plasma with Energy Correlators

1. Jets modification and medium response

Oral presentation

Energy-energy-correlators (EEC’s) are a promising observable to study the dynamics of jet evolution in the quark-gluon plasma (QGP) through its imprint on angular scales in the energy flux of final-state particles. We carry out the first complete calculation of EEC’s using realistic simulations of high-energy heavy-ion collisions, and dissect the different dynamics underlying the final...
