Jet Reconstruction in Heavy Ion Collisions
read the original abstract
We examine the problem of jet reconstruction at heavy-ion colliders using jet-area-based background subtraction tools as provided by FastJet. We use Monte Carlo simulations with and without quenching to study the performance of several jet algorithms, including the option of filtering, under conditions corresponding to RHIC and LHC collisions. We find that most standard algorithms perform well, though the anti-kt and filtered Cambridge/Aachen algorithms have clear advantages in terms of the reconstructed transverse-momentum offset and dispersion.

Energy-energy correlators in p-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV
First measurement of two-point EEC in 20-80 GeV/c charged jets in p-Pb collisions shows modification relative to pp at the same energy, with enhancement at large angles and suppression at small angles in the 20-40 GeV...

Measurements of jet quenching with semi-inclusive hadron-jet correlations in Ru+Ru and Zr+Zr collisions at $\sqrt{s_\mathrm{NN}}=200$ GeV
Suppression of recoil jet yields and intra-jet broadening is observed in central Ru+Ru and Zr+Zr collisions, indicating medium-induced partonic energy loss.
