“…(1), may be written as linear combinations of the hadronic structure functions F 2 , F γZ 2,3 , and F Z 2,3 , containing information on the QCD parton dynamics as well as the electroweak couplings of the quarks to the neutral vector bosons. The function F 2 is associated with pure photon exchange terms, F γZ 2,3 correspond to photon-Z 0 interference and F Z 2,3 correspond to pure Z 0 exchange terms. In addition, the longitudinal structure functionF L may be similarly decomposed.F L is important only at high y and is expected to be negligible at large x and Q 2 .…”

“…They are combined with previously published H1 measurements [2,3] from HERA I. These combined unpolarized cross sections make use of the complete HERA data set collected by H1 and amounts to a total luminosity of 165.5 pb −1 for e − p scattering and 280.8 pb −1 for e + p scattering.…”

The inclusive deep inelastic cross sections are measured for the neutral current process, e ± p → e ± X, in interactions with longitudinally polarised lepton beams of HERA II at large negative fourmomentum transfer squared Q 2 ≥ 150 GeV 2 . The polarisation asymmetries of the neutral current e − p and e + p cross sections are presented. The cross sections are combined with previously published data from H1 to obtain the most precise unpolarised measurements. The lepton charge asymmetry of the unpolarised cross sections is used to extract the structure function xF γZ 3. The measurements are found to be in agreement with the Standard Model expectations.

Abstract. A review of the ATLAS measurements sensitive to parton distribution functions is presented. The analyses use proton-proton collision data at center-of-mass-energy √ s = 7 TeV collected at the Large Hadron Collider between April and November 2011. When included in QCD fits, the ATLAS data allow for improving the experimental constraints on the gluon and strange-quark parton density functions of the proton.

Abstract. A successful description of hadron-hadron collision data demands a profound understanding of quantum chromodynamics. Inevitably, the complexity of strong-interaction phenomena requires the use of a large variety of theoretical techniques-from perturbative cross-section calculations up to the modelling of exclusive hadronic final states. Together with the unprecedented precision of the data provided by the experiments in the first running period of the LHC, a solid foundation of hadron-hadron collision physics at the TeV scale could be established that allowed the discovery of the Higgs boson and that is vital for estimating the background in searches for new phenomena. This chapter on studies of quantum chromodynamics at the LHC is part of a recent book on the results of LHC Run 1 [1] and presents the advances in theoretical methods side-by-side with related key measurements in an integrated approach.
