Parton energy-momentum exchange with the quark gluon plasma (QGP) is a multi-scale problem. In this work, we calculate the interaction of charm quarks with the QGP within the higher twist formalism at high virtuality and high energy using the MATTER model, while the low virtuality and high energy portion is treated via a (linearized) Boltzmann Transport (LBT) formalism. Coherence effect that reduces the medium-induced emission rate in the MATTER model is also taken into account. The interplay between these two formalisms is studied in detail and used to produce a good description of the D-meson and charged hadron nuclear modification factor RAA across multiple centralities. All calculations were carried out utilizing the JETSCAPE framework.

  1. Extraction of jet-medium interaction details through jet substructure for inclusive and gamma-tagged jets

    hep-ph 2025-06 conditional novelty 4.0 of 10

    In JETSCAPE simulations, gamma-tagged jets reveal a genuine medium-induced broadening of quark-jet hard splittings, while the narrowing seen for inclusive jets is largely a selection bias from energy loss.
