Probing quark-gluon matter with jets

23 Jul 2018, 08:00 → 27 Jul 2018, 20:00 US/Eastern

Large Seminar Room (BNL)

Megan Connors (Georgia State University RBRC), Yacine Mehtar-Tani (INT, University of Washington), Brian Page (Brookhaven National Laboratory), Felix Ringer (Los Alamos National Laboratory), Konrad Tywoniuk (CERN), Marta Verweij (Vanderbilt University / RIKEN BNL Research Center)

Observables involving QCD jets have proven to be effective in probing the hot nuclear medium created in heavy ions collisions. In the last decade important theoretical and experimental advances have been achieved towards understanding jet evolution in QCD media, stimulated by jet measurements at RHIC and LHC.

Novel substructure techniques that were developed recently within the high-energy community have also draw much attention in the context of heavy ion collisions and are currently being investigated. While the latter efforts are mainly attempting to describe final-state interactions, jets in electron-ion collisions constitute comprehensive tools for probing the nuclear structure.

The workshop aims at bringing together leading experts form the heavy ion and the high energy communities, theorists and experimentalists, to review the latest progress jet physics in the various subfields, share their respective expertise and discuss the related technical challenges. The goal is to provide a platform to assess the new jet observables whose scope is probing quark-gluon matter.

The workshop will cover the following topics:

• Jet quenching in heavy ion collisions and small systems

• Jets in eA collisions   

• Jet substructure

• Monte Carlo implementations

32 Seminar: Jet fragmentation in a QCD plasma: Universal quark/gluon ratio and wave turbulence

We investigate the radiative break-up of a highly energetic quark or gluon in a high-temperature QCD plasma. Within an inertial range of momenta T ? << p << ? E, where E denotes the energy of the original hard parton (jet) and T the temperature of of the medium, we find that, as a result of the turbulent nature of the underlying parton cascade, the quark to gluon ratio of the soft fragments tends to a universal constant value that is independent of the initial conditions. We discuss implications of this result to jet quenching physics and the problem of thermalization of the quark-gluon plasma in heavy ion collisions.
