ALICE 2017 luminosity determination for pp collisions at $\sqrt{s}$ = 5 TeV

Luminosity determination in ALICE is based on visible cross sections measured in van der Meer scans. In November 2017, the Large Hadron Collider provided proton-proton collisions at a centre-of-mass energy of $\sqrt{s}$ = 5 TeV. A van der Meer scan was performed, in which the cross section was measu...

Sumario:Luminosity determination in ALICE is based on visible cross sections measured in van der Meer scans. In November 2017, the Large Hadron Collider provided proton-proton collisions at a centre-of-mass energy of $\sqrt{s}$ = 5 TeV. A van der Meer scan was performed, in which the cross section was measured for two classes of visible interactions, based on particle detection in the ALICE luminometers: the T0 detector with pseudorapidity coverage $4.6<\eta< 4.9$, $-3.3<\eta<-3.0$ and the V0 detector with pseudorapidity coverage $2.8<\eta< 5.1$, $-3.7<\eta<-1.7$. This document describes the experimental setup for such a measurement and reports its results.
