The accurate determination of the parton distribution functions (PDFs) of the proton is an
essential ingredient of the Large Hadron Collider (LHC) program. PDF uncertainties impact …

Extensive experimental and theoretical explorations over the last decades showed that the
nucleon (proton/neutron) is not just a simple system of 3 quarks bound by gluons, but a …

The algorithms used by the ATLAS Collaboration to reconstruct and identify prompt photons
are described. Measurements of the photon identification efficiencies are reported, using 4.9 …

We present the first determination of parton distributions of the nucleon at NLO and NNLO
based on a global data set which includes LHC data: NNPDF2. 3. Our data set includes …

A bstract We present next-to-leading order (NLO) predictions including QCD and
electroweak (EW) corrections for the production and decay of off-shell electroweak vector …

A bstract In this publication, uncertainties in and differences between the MC@ NLO and P
OWHEG methods for matching next-to-leading order QCD calculations with parton showers …

Results of a search for physics beyond the Standard Model in events containing an
energetic photon and large missing transverse momentum with the ATLAS detector at the …

A bstract We present a fully automated implementation of next-to-leading order electroweak
(NLO EW) corrections in the O pen L oops matrix-element generator combined with the …

A bstract We present an implementation of the so-called Ckkw-l merging scheme for
combining multi-jet tree-level matrix elements with parton showers. The implementation …

A search for squarks and gluinos in final states containing jets, missing transverse
momentum and no high-p T electrons or muons is presented. The data represent the …
