Abstract

The present status and the future of hadron production characterization in Pb–Pb collisions at LHC by measuring the p_T dependence of baryon over meson ratios is presented. The current RHIC and LHC results showing a strong enhancement of the Λ/K_S⁰ ratio in Pb–Pb collisions with respect to proton-proton collisions at intermediate p_T and their interpretation in terms of coalescence processes are discussed. A crucial extension of these studies to heavy flavor hadrons (D, B mesons and Λ_c, Λ_b baryons) will be enabled by the foreseen reforging of the ALICE Inner Tracking System (ITS). The main performance objectives and technological ingredients of the ITS upgrade are summarized.
