Abstract
The recent ALICE results on hard probes, focusing on open heavy flavor, quarkonia, and jet measurements in pp and Pb--Pb collisions are presented. During the LHC Run 3, the continuous readout of the upgraded Time Projection Chamber (TPC) with GEM technology, along with improved tracking from ITS2 and the newly installed Muon Forward Tracker (MFT), have enabled high-precision studies of quarkonia and heavy flavour production, and jet modification in the quark-gluon plasma (QGP). These new measurements provide crucial constraints on parton energy loss mechanisms and heavy-quark dynamics in hot QCD matter. Future upgrades planned for Run 4, as well as the long-term ALICE 3 with an all-silicon tracking system, will further enhance the ability to study the properties of QGP with unprecedented accuracy.
