Abstract
In late 2017, the ALICE experiment recorded a data sample of Xe--Xe
collisions at the unprecedented energy in A--A systems of $\sqrt{s_{\rm{NN}}} = 5.44\text{ TeV}$.
The $p_{\rm T}$ spectra at mid-rapidity ($|y| < 0.5$) of
pions, kaons and protons are presented. The preliminary $p_{\rm T}$ 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 paper focuses on 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 this data set comes from the experimental
conditions: because of the lower magnetic field of
the ALICE solenoid ($B = 0.2\text{ T}$, lower than
the nominal $0.5\text{ T}$) we expect to explore a $p_{\rm T}$ region
unattainable before. A comparison between the yields at different centrality
bins will also be provided.
