Event-by-event physics in ALICE

Event-by-Event (E-by-E) fluctuations are one of the main dynamical probes of the phase transition from ordinary hadronic matter to a plasma of quarks and gluons, which is expected to occur in ultra-relativistic heavy-ion collisions. In this article, the results of a study concerning the observability of E-by-E fluctuations for the ALICE experiment at the LHC collider at CERN is presented. In particular, an estimate of the ALICE E-by-E statistical sensitivity in the measurement of the mean transverse momentum of charged hadrons, of the inverse slope parameter from the hadron transverse momentum spectra, and of their particle ratios is discussed. The analysis relies on the excellent performance of ALICE in terms of particle identification.
