Abstract
ALICE (A Large Ion Collider Experiment) at the CERN Large Hadron Collider (LHC) is designed to study p-p and Pb-Pb collisions at ultra-relativistic energies. ALICE is equipped with a Muon Spectrometer (MS) to study the heavy charmonia in p-p and heavy ion collisions via their muonic decay. At first, in the LHC Run 1 and 2 the selection of interesting events for muon physics in the MS was performed with a dedicated Muon Trigger system based on Resistive Plate Chambers (RPCs) operated in maxi-avalanche mode. During the Long Shutdown 2 (LS2) of LHC ALICE underwent a major upgrade of its apparatus: since Run 3 (started in July 2022), in order to fully profit from the increased luminosity of Pb-Pb collisions (from 20 kHz in Run 2 to 50 kHz in Run 3), the ALICE experiment is running in continuous readout (triggerless) mode and the Muon Trigger became the Muon IDentifier (MID). In order to…
