Abstract
Key features of jet-medium interactions in heavy-ion collisions are modifications to the jet structure. Recent results from experiments at the LHC and RHIC have motivated several theoretical calculations and Monte Carlo models towards predicting these observables simultaneously. In this proceedings, the recoil picture in JEWEL is summarized and two independent procedures through which background subtraction can be performed in JEWEL are introduced. Information of the medium recoil in JEWEL significantly improves its description of several jet shape measurements.
Highlights
The qualitative effect of jet quenching through the measurements of the jet nuclear modification factor (RAA) are confirmed with Run1 data at the LHC [1, 2, 3]
Jets thats propagate the quark gluon plasma (QGP) were perceived as getting broader, losing energy inside the jet cone, increased multiplicity of low transverse momenta particles around the periphery of the jet and several other consistent observations when compared to jets in pp collisions
The subjet groomed momentum fraction was recently measured as a function of the jet pT and event centrality at CMS [10], concluding that jets were more asymmetrically split in heavy-ion collisions as opposed to those in pp collisions. All these aforementioned results point to quantitative features of jet quenching, it is imperative that any phenomenological model describing the physics of QGP has to predict the general behavior and trend of these observables
Summary
The qualitative effect of jet quenching through the measurements of the jet nuclear modification factor (RAA) are confirmed with Run1 data at the LHC [1, 2, 3]. When comparing data with Jewel (including recoils), a slight mismatch appears for inter-jet observables due to the experimental implementation of the background subtraction.
