Comparing the MARTINI and CUJET models for jet-quenching: Medium modification of jets and jet substructure

Understand

Jets produced by the initial hard scattering in heavy ion collision events lose energy due to interactions with the color-deconfined medium formed around them: the quark-gluon plasma (QGP).

• Jet-medium interactions constitute an important theoretical and experimental field for studies of QGP, and various models with different assumptions have been proposed to describe them.
• A fair and direct comparison of these models requires that all other aspects of the simulation be fixed, which is achieved in this work by relying on the JETSCAPE framework.
• We employ JETSCAPE to directly and comprehensively compare two successful energy loss models: CUJET and MARTINI.
