The research program on Quark-Gluon Plasma (a deconfined state of nuclear matter) is on the verge of considerably extending with the restart of lead-lead collisions at the highest energy (= 5,36 TeV). On September 26th 2023, the LHC delivered lead beams with collision rates between 2 and 6 kHz; the goal is to reach quickly rates of about 50 kHz. This data taking period will stop at the end of October. During this period of LHC Run 3, the cumulated statistics will be 10-fold that of Run 1 (2010-2013) and Run 2 (2015-2018) all together. Those data are crucial for the ALICE experiment because they will allow to reach the core of the physics program on Quark-Gluon Plasma with a better precision but, above all, new observable thanks to the upgrades installed during the last long shutdown (2018-2022).
