Description
Cross section measurements are an essential part of the ALICE physics program and require precise knowledge of the luminosity delivered by the LHC. In ALICE, the luminosity determination relies on visible cross sections measured in dedicated calibration sessions, the van der Meer scans.
In this talk, the methodology and results of the luminosity measurement will be discussed. For the LHC Run 2 data samples, ALICE measured the luminosity with an uncertainty better than 2% for pp collisions and 3% for Pb-Pb collisions.
The first measurement of the inelastic hadronic cross section for Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV, obtained by efficiency correction of the visible cross section, will also be presented and compared with available models. The luminosity-related upgrades to the ALICE detector for the LCH Run 3 will be presented.
