dc.description.abstract | A measurement of the Drell-Yan fiducial cross section in the dimuon
channel is presented differentially in terms of dimuon invariant mass,
double differentially in terms of dimuon invariant mass and rapidity
and double differentially in terms of dimuon invariant mass and muon
separation . The cross sections are measured using 20:3 fb1 of
ATLAS data taken during 2012 at a centre of mass energy of ps = 8 TeV.
Dedicated studies determining muon performance corrections for monte
carlo isolation and trigger efficiencies and techniques for estimating backgrounds
using data driven methods are described in detail. The fiducial
cross sections agree within 10% of theoretical predictions in the regions
where the statistical uncertainties are subdominant. Excluding the systematic
uncertainty associated with the detector luminosity, a systematic
uncertainty of below 2.5% is observed for the m < 300 GeV region
for both the single and double differential cross section measurements.
Theoretical predictions to NNLO in QCD including NLO higher order
electroweak effects and a photon induced process component are found to
underestimate the measurement by 3%. For the m < 300 GeV region
the uncertainty of the measurement is smaller or of the same order as the
theoretical predictions, which indicates that the results will provide useful
information into the constraining and tuning of future physics models. | en_US |
