Measurement of the Production Cross-Section of Z u+u- with ATLAS at the LHC at Vs=7 TeV.

[摘要] This thesis presents measurements of the inclusive process pp->(Z->mu+mu-)+anything based on 40.2~pb^-1 of data from LHC collisions with center-of-mass energy of sqrt(s)=7 TeV as recorded by the ATLAS detector.For events with two isolated muons satisfying transverse momentum (p_T)_mu>20 GeV, pseudorapidity |(eta)_mu|<2.4, and dimuon invariant mass 60mu+mu- muon pairs were also measured and found to be in good agreement with theory modeled by the PYTHIA Monte Carlo program.
