ALICE 3 – A Next-Generation Heavy-Ion Experiment — •Sebastian Scheid for the ALICE collaboration — Goethe University, Frankfurt, Germany

In this contribution we will present ALICE 3, a detector proposed for the next-generation heavy-ion program in LHC Run 5 and 6. The innovative detector concept, will give access to novel measurements of electromagnetic and hadronic probes of the QGP at very low momenta that will remain inaccessible in LHC Run 3 and 4. This includes the multi-differential measurement of thermal dileptons, that provide insight on the early phases of the medium formation. The measurement of multi charm states and exotic objects in the heavy flavour sector, as well as the correlation of heavy-flavour hadrons can be used to gain information on the hadronisation and strong interaction processes.

To achieve these measurements the detector has to provide tracking and particle identification down to lowest transverse momenta with an unprecedented pointing resolution while keeping the material budget to a minimum.
