ALICE 2016-2017-2018 luminosity determination for pp collisions at $\mathbf{\sqrt{{\textit s}}}$ = 13 TeV

Luminosity determination in ALICE is based on the measurement of visible cross sections in van der Meer (vdM) scans. In the Run 2 (2015--2018), the Large Hadron Collider provided proton-proton collisions at a centre-of-mass energy of $\hbox{$\sqrt{s} = 13$ TeV}$. One vdM scan per year was performed,...

Sumario:Luminosity determination in ALICE is based on the measurement of visible cross sections in van der Meer (vdM) scans. In the Run 2 (2015--2018), the Large Hadron Collider provided proton-proton collisions at a centre-of-mass energy of $\hbox{$\sqrt{s} = 13$ TeV}$. One vdM scan per year was performed, which allowed for calibration of the ALICE luminometers: the T0 detector with pseudorapidity coverage $\hbox{$4.6<\eta< 4.9$}$, $\hbox{$-3.3<\eta<-3.0$}$, and the V0 detector with pseudorapidity coverage $\hbox{$2.8<\eta< 5.1$}$, $\hbox{$-3.7<\eta<-1.7$}$. This document presents the luminosity determination methodology and results for the years 2016, 2017 and 2018.
