We investigate the effect of PT-broadening on jet substructure observables in heavy-ion collisions at the LHC. As an example, we focus on the opening angle of the two branches that satisfy the soft drop grooming condition in a highly energetic jet. The medium modification of the angular distribution can provide important information on the jet transport properties of hot QCD matter. In addition, we take into account a change of the overall fraction of quark and gluon jets in heavy-ion collisions. We comment on the comparison to a recent measurement from the ALICE Collaboration.

  1. Extracting Essential Non-perturbative Information in Jet Invariant Mass via the Bayesian Analysis

    hep-ph 2025-07 conditional novelty 7.0 of 10

    A new 3D non-perturbative jet-mass model, fitted to pp data, separates hadronization, ISR, and underlying-event effects and correctly predicts e+e- jet mass data.

  2. Constraining the Resolution Length of Quark-Gluon Plasma with New Jet Substructure Measurements

    hep-ph 2025-09 conditional novelty 6.0 of 10

    Jet substructure measurements from ALICE and ATLAS, modeled with the Hybrid Model, disfavor both fully coherent and fully incoherent energy loss, implying a finite QGP resolution length near 1/(pi T).
