Jets can be used to study in-medium modifications of the parton shower and the energy loss mechanisms in heavy ion collisions. Several recent works at LHC have hinted that quark and gluon fractions in measured jets may be modified in QGP due to quenching. Jet charge is defined as the momentum-weighted sum of charges of particles inside a jet. It is sensitive to the charge of the initiating...
Recent ALICE measurements of jet splittings in Pb—Pb and pp collisions using the new 2018 data at
Parton energy loss has been established as an essential signature of the QGP in heavy ion collisions since the earliest measurements at RHIC indicating suppression of hadron spectra at high
Jets engender physics over a multitude of scales, from the hardest interactions in a heavy-ion collision (up to a TeV at the LHC), down to the scale of the freeze-out temperature. A complete description of jet modification must address the role and interplay of the physics at each of these scales and their effect on a wide variety of integrated and differential jet observables.
In this...
The observed suppression of inclusive jets in heavy-ion collisions at LHC has a very weak
The spatial anisotropy of QGP, formed in ultrarelativistic heavy-ion collisions, is commonly inferred form models of early QGP evolution. These studies (e.g. MC-Glauber, EKRT, IP-Glasma, MC-KLN), based on different methods, lead to notably different predictions, with a notable effect in the resulting predictions for both low and high pt data. On the other hand, energy loss of high-pt particles...
