QGP, heavy-ion, LHC, ALICE, ALICE 3Abstract
The ALICE experiment is devoted to the study of the quark-gluon plasma (QGP) created in heavy-ion collisions at the CERN LHC. The experimental setup allows for the study of many different observables that contributed to the characterization of the properties of the QGP. The ALICE experiment went through a major upgrade during LS2 to profit from the increased LHC luminosity and to improve the tracking resolution. An additional upgrade is planned for LS3. A new experiment, ALICE 3, was proposed as next major upgrade in LS4. In this contribution, a selection of recent physics results was presented together with a glimpse of the next upgrades during LS3 and LS4, with the main focus on ALICE 3 and its physics program
