Several measurements performed by the ATLAS collaboration are either
useful to constrain the proton structure or are affected by its
associated uncertainties.
The strange-quark density is rather poorly known at low x. Measurements
of the W+c production and the inclusive W and Z differential cross
sections are found to constrain the strange-quark density. Drell-Yan
cross section...

Recent developments in the fast reproduction of the results of QCD
calculations using the APPLgrid project are presented. The calculation
of cross-sections at Next-to-Leading order in QCD involves the
integration over the final state phase space in order to cancel the
infra-red divergences. For the calculation of cross sections for
observables at hadron-hadron colliders this integration...

Hard QCD
The precise calculation of hadron-hadron collisions at higher orders of
perturbative QCD requires a large amount of processing power.
In addition, thorough analyses require that these calculations are
repeated many times for different parameters.
The fastNLO toolkit can be interfaced with next-to-leading order (NLO)
and next-to-next-to-leading order (NNLO) Monte-Carlo programs to...

Hard QCD
The ATLAS Collaboration has performed precision measurements of the transverse momentum of Z/gamma* bosons and their decay lepton angular decorrelation with the phi* observable. Measurements have been performed at 7 and 8 TeV in different dilepton invariant mass and rapidity regions. These measurements are sensitive to soft resummation effects and hard jet emissions for small and large...

The production of W and Z bosons is studied in pp collisions at a center-of-mass energy of 8 TeV using data collected in the CMS experiment. W events are selected containing an isolated, energetic electron or muon. Z events are selected containing a pair of isolated, energetic electrons or muons. Data-driven methods are used to estimate reconstruction and triggering efficiencies, and well as...
