Study of Z production in PbPb and pp collisions $\sqrt{s_{NN}}=$2.76 TeV in the dimuon and dielectron decay channels University of Antwerp Vrije Universiteit Brussel Ghent University
The production of Z bosons is studied in the dimuon and dielectron decay channels in PbPb and pp collisions at root s(NN) = 2.76TeV, using data collected by the CMS experiment at the LHC. The PbPb data sample corresponds to an integrated luminosity of about 166 mu b(-1), while the pp data sample collected in 2013 at the same nucleon-nucleon centre-of-mass energy has an integrated luminosity of 5.4 pb(-1). The Z boson yield is measured as a ...
