Description
The measurement of Z bosons in heavy ion collisions is an excellent
tool for probing the nucleus at the partonic level. The inclusive
yield provides a stringent test of binary collision scaling. Recent
ATLAS results demonstrate such scaling in Pb+Pb collisions. The 2013
p+Pb physics run at the LHC providing more than 30 nb^-1 of collisions
at an energy of sqrt(s_NN)=5.02 TeV has made a detailed study of Z
boson production in proton+nucleus interactions possible for the first
time. These data may confirm binary scaling in the p-Pb system and
help clarify the present ambiguity of centrality classifications in
proton+nucleus collisions. Further, the momentum and rapidity
differential yields of Z bosons allow the detection of any
modification of the initial state present in such collisions.
The ATLAS experiment allows the analysis of Z boson production via the
di-electron and di-muon channels over a wide acceptance in
rapidity. We will present the Z boson yield measured by the ATLAS
experiment in p+Pb collisions at the LHC.
