protons and lead ions, and begun with centred orbits with different revolution frequencies, and then separately ramped to the accelerator's maximum collision energy. The first lead-proton run at the LHC lasted for one month and data help ALICE physicists to decouple the effects of the plasma from effects that stem from cold nuclear matter effects and shed more light on the study of the Quark-Gluon plasma. In the case of lead-lead collisions, the configurations of the quarks and gluons that make up the protons and neutrons of the incoming lead nucleus can be somewhat different of those in the incoming protons. In order to study if part of the effects we see when comparing lead-lead and proton-proton collisions is due to this configuration difference rather than the formation of the plasma. Proton-lead collisions are an ideal tool for this study. The ALICE detectors A key design consideration of ALICE is the ability to study QCD and quark (de)confinement under these extreme conditions. This is done by using particles, created inside the hot volume as it expands and cools down, that live long enough to reach the sensitive detector layers situated around the interaction region. ALICE's physics programme relies on being able to identify all of them, i.e. to determine if they are electrons, photons, pions, etc. and to determine their charge. This involves making the most of the (sometimes slightly) different ways that particles interact with matter. 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. In order to identify all the particles that are coming out of
