Full jet RAA at 5.02 TeV, R=0.2 with comparisons to JEWEL, LBT, SCETG, and Hybrid Model. Anti-kT, |eta|<0.5, 0-10% centrality. Leading charged track with pT > 5 GeV is required in both Pb-Pb and reference spectra in the measured data..

JEWEL [arXiv:1212.1599] predictions are provided with and without recoils [arXiv:1707.01539]. In the case of including the recoils, background is subtracted using the “4MomSub” scheme. The JEWEL predictions have been provided courtesy of Ritsuya Hosokawa (University of Tsukuba), and use T = 440 MeV and t0 = 0.4 fm/c [arXiv:1608.03099]. Note that these predictions do not include systematic errors, but rather only statistical uncertainties. Leading track requirements are applied as in the measured data.

Linear Boltzmann Transport (LBT) model [arXiv:1503.03313] calculations for our measurement are provided in [arXiv:1809.02525]. The initial jet shower is produced by Pythia 8, neglecting nuclear modification of the PDF. These then interact with the evolving QGP through the LBT model description above. The QGP evolution itself is described by the CLVisc 3+1D hydrodynamic model, including event-by-event initial conditions. Hadronization of jet and medium partons is described by a parton recombination model as outlined in [arXiv:1809.02525]. The calculation uses a background subtraction scheme described in [arXiv:1809.02525], with only the need to address background from the pp event and jet-induced medium response. No systematic uncertainties were provided for this calculation. No leading track requirement is applied.

Soft Collinear Effective Theory with Glauber gluons (SCETG) [arXiv:1701.05839, arXiv:1801.00008] predictions are provided by Dr. Haitao Li (LANL), according to [arXiv:1701.05839] but with further improvements. The pp jet cross-section is computed to NLO in αs, and with a LL resummation in jet R. Medium effects are computed at NLO, but without (yet) a resummation in jet R. The in-medium splitting functions described above include radiative processes, but these predictions have not yet included collisional energy loss. Note that this could have significant impact particularly on the larger radius jets, where it may increase suppression. The EFT coupling constant between the medium and jets is g = 2.0. The medium is evolved using 2+1D viscous hydrodynamics. For pp the CT14nlo PDF is used, and for Pb–Pb, the nCTEQ15FullNuc PDF is used. Energy loss in cold nuclear matter is also taken into account. The plotted error band represents the systematic uncertainty obtained by scale variations. No leading track requirement is applied.

In the Hybrid model [arXiv:1405.3864, arXiv:1508.00815, arXiv:1609.05842, arXiv:1707.05245], The parameter κsc is the main free parameter in the model, and is fit to ATLAS and CMS hadron and jet data [arXiv:1808.07386]. Two values of the parameter Lres, describing the scale at which the medium can resolve two split partons, are provided. The model accounts for this and includes a wake in the direction of the jet [arXiv:1609.05842]. The predictions are provided by Dr. Daniel Pablos (McGill University). A leading track cut of 5 GeV was applied for all predictions. The plotted error band represents theπT combination of statistical and systematic uncertainties.
