In late 2017, the ALICE experiment recorded a data sample of Xe-Xe collisions at the unprecedented energy in A-A systems of √ s NN = 5.44 TeV. The p T spectra at mid-rapidity (|y| < 0.5) of pions, kaons and protons are presented. The preliminary p T spectra are obtained by combining independent analyses with the Inner Tracking System (ITS), the Time Projection Chamber (TPC), and the Time-Of-Flight (TOF) detectors. This paper focuses on the details of the analysis performed with TOF and in

The peculiarity of this data set comes from the experimental conditions: because of the lower magnetic field of the ALICE solenoid (B = 0.2 T, lower than the nominal 0.5 T) we expect to explore a p T region unattainable before. A comparison between the yields at different centrality bins will also be provided.
