STAR reports 20% suppression of recoiling hadrons and jets in high-event-activity O+O collisions at 200 GeV, with a measured 0.7 GeV/c pT shift for large-radius jets, providing evidence for jet quenching in small systems.
The work presents a dispersive fit for the refractive index of liquid argon incorporating anomalous dispersion and proposes jet drift in simulations of heavy-ion collisions as a way to disentangle medium properties from energy loss.
An LSTM model trained on simulated jet substructure learns to predict true jet energy loss and distinguishes quenching signatures even after realistic detector effects are applied.
Preliminary simulations show charm quarks lose significantly less transverse momentum in a fluctuating color string medium than in the hydrodynamic expansion of the EPOS4HQ model.
Color dipole calculations of the ratio of exclusive vector meson to inclusive jet/hadron photoproduction cross sections in UPC pA and AA collisions at LHC Run 4, including the double ratio R_UPC proposed for saturation studies.
