Description

At the Large Hadron Collider (LHC), at CERN, we are able to create the hottest and the densest conditions which are similar to those at the beginning of the Universe. During the past ten years, we observed the existence of Quark Gluon Plasma (QGP) which is formed at the early stages of heavy ion collisions. The measurements we obtained led to significant progress for understanding its properties through Pb-Pb or Xe-Xe collisions, but also from even smaller systems such as p-Pb. During the Long Shutdown 2, ALICE experiment undergone major upgrades for both hardware and software components. On July 5$^{th}$ 2022, LHC entered in the era of Run 3 establishing a milestone for ALICE which will collect data at an interaction rate 50 times larger than before. The two main goals are to record data much faster comparing with Run 1 & 2, and to enhance the track reconstruction efficiency and precision for the detection of short-lived particles containing heavy-flavour quarks. ALICE detector has close to 13 billion electronic sensor elements with a continuous read out, creating a data stream of more than 3.4 terabytes per second. The new computing scheme for Run 3 replaces the traditionally separate online and offline frameworks by a unified one, which is called O$^2$. Around 500 billion minimun bias events of p-p collisions were collected during 2022, and about 12 billion reconstructed events of five weeks Pb-Pb in 2023.
