  4. 4. HI-specific vdM-calibration issues (ALICE Speaker)
    Martino Gagliardi (Universita e INFN Torino (IT))
    10/03/2025, 16:00

    For instance: fitting procedures with challenging scan shapes;
    dealing with low-statistics in scan tails; BCID-dependent satellite
    corrections; satellite collisions; NF corrections; use of ZDC as
    high-statistics L monitor
    Include HI-specific contributions from All experiments
