Titel Measurement of the inclusive Z + bb cross section in pp-collisions at 7 TeV with ATLAS
Autor Dennis Hellmich
Publikationsform Dissertation
Abstract In this thesis, the measurement of the inclusive cross section of the production of two b-jets in association with a Z boson is measured where the Z can decay to an electron-positron pair or to a muon-antimuon pair. The analysed data was recorded by the ATLAS experiment in 2011 at a centre-of-mass energy of sqrt(s) = 7 TeV and includes 4.58 fb-1 of proton-proton collisions. The resulting cross sections are unfolded to particle level and compared to LO and NLO predictions from different Monte Carlo generators. Relevant systematic uncertainties have been studied. The measurement has been found to be in agreement with NLO predictions within the quoted uncertainties.
