In a "traditional" experiment, particles are identified or at least assigned to families (charged or neutral hadrons), by the characteristic signatures they leave in the detector. The experiment is divided into a few main components and each component tests a specific set of particle properties. These components are stacked in layers and the particles go through the layers sequentially from the collision point outwards: first a tracking system, then an electromagnetic (EM) and a hadronic calorimeter and finally a muon system. The detectors are embedded in a magnetic field in order to bend the tracks of charged particles for momentum and charge determination. This method for particle identification works well only for certain particles, and is used for example by the large LHC experiments ATLAS and CMS. However, this technique is not suitable for hadron identification as it doesn't allow distinguishing the different charged hadrons that are produced in Pb-Pb collisions.
