Identifying quenched jets in heavy ion collisions with machine learning

Journal of High Energy Physics, 2023
Measurements of jet substructure in ultra-relativistic heavy ion collisions suggest that the jet showering process is modified by the interaction with the quark-gluon plasma. Modifications of the hard substructure of jets can be explored with modern data-

Resolving extreme jet substructure

Journal of High Energy Physics, 2022
AbstractWe study the effectiveness of theoretically-motivated high-level jet observables in the extreme context of jets with a large number of hard sub-jets (up toN= 8). Previous studies indicate that high-level observables are powerful, interpretable tools to probe jet substructure forN≤ 3 hard sub-jets, but that deep neural networks trained on low ...

Hadronic calorimeter shower size: Challenges and opportunities for jet substructure in the superboosted regime

Physics Letters B, 2016
Hadrons have finite interaction size with dense material, a basic feature common to known forms of hadronic calorimeters (HCAL). We argue that substructure variables cannot use HCAL information to access the microscopic nature of jets much narrower than ...

Unbinned deep learning jet substructure measurement in high Q2 ep collisions at HERA

Physics Letters B, 2023
The radiation pattern within high energy quark- and gluon-initiated jets (jet substructure) is used extensively as a precision probe of the strong force as well as an environment for optimizing event generators with numerous applications in high energy ...

Modification of jet substructure in heavy ion collisions as a probe of the resolution length of quark-gluon plasma

Journal of High Energy Physics, 2020
We present an analysis of the role that the quark-gluon plasma (QGP) resolution length, the minimal distance by which two nearby colored charges in a jet must be separated such that they engage with the plasma independently, plays in understanding the ...
