Particle identification with the ALICE detector

This paper describes the particle identification (PID) capability of the ALICE detector. ALICE makes use of several particle discrimination techniques to address successfully the challenge of identifying particles in high-density events produced in Pb–Pb interactions at LHC energies. The combination of several sub-detectors makes the measurement more robust and wider in momentum, allowing the detector to use the PID as a key tool for the complete understanding of heavy-ion collisions at LHC.
