A Large Ion Collider Experiment (ALICE) is one of the four large experiments at the Large Hadron Collider (LHC), the accelerator built at CERN where protons and Pb ions are accelerated to the highest energies ever reached. This chapter is devoted to the description of ALICE, which is the experiment dedicated to the study of the Quark-Gluon Plasma. In Sect. 3.1 the LHC main features are introduced, together with some parameters of the proton and heavy-ion beams that are relevant for the study presented in this thesis. An overview of the ALICE setup is given in Sect. 3.2, focusing on the detectors that are used for the reconstruction of D meson decays. Sections 3.3 and 3.4 are devoted to the description of the ALICE tracking strategy and of the particle identification signals and techniques which allow to deal with the extremely-high multiplicity environment of Pb–Pb collisions. In Sect. 3.5 one of the most important variables for the reconstruction of heavy-flavour particles, the track impact parameter, is described.
