Stability of the ALICE-HMPID detector in LHC Run 1 and 2 and PID performance in p-Pb collisions at √sNN = 8.02 TeV

The stability and the performance of the High Momentum Particle Identification Detector (HMPID), present in the A Large Ion Collider Experiment (ALICE) at the Large Hadron Collider (LHC) at CERN, were studied. The stability was investigated by analysing data obtained in 2018 and thus improving the statistics already analysed for Run 2, making the detector stability study up to date. The PID performance of the detector was studied for p-Pb collisions at √sNN = 8.02 TeV, which data were collected in 2016. Finally, the evaluation of the pions, kaons and protons pT spectra for minimum biased p-Pb collisions at √sNN = 8.02 TeV were obtained.
