Description

In late 2017, the ALICE collaboration recorded data from Xe-Xe collisions at the unprecedented energy in AA systems of $\sqrt{s_{\rm{NN}}} = 5.44$ TeV. The $p_{\rm T}$-spectra at mid-rapidity ( $|y| < 0.5$ ) of pions, kaons and protons are presented.
The final $p_{\rm T}$-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 presentation focuses in the details of the analysis performed with TOF and in particular on the performance implications of the special Xe-Xe run conditions.
The peculiarity of these data comes from the experimental conditions: because of the lower magnetic field ($B = 0.2 \text{ T}$, less than the usual $0.5 \text{ T}$) we expect to explore a $p_{\rm T}$ region unattainable before.
A comparison between the yields at different centrality bins will also be provided.
