Using 7.3 pb-1 the distribution of the variable $\phi^*$ is measured, which probes the same physical effects as the $Z/\gamma^*$ boson transverse momentum, but is less susceptible to the effects of experimental resolution and efficiency. Results are presented for both the di-electron and di-muon channel.

Correlations in the azimuthal angle between the two largest pT jets have been measured using the D0 detector in ppbar collisions at 1960~GeV. The analysis is based on an inclusive dijet event sample in the central rapidity region. The correlations are determined for four different pT intervals.

Measurement of jet shapes in inclusive jet production in p pbar collisions at center-of-mass energy sqrt(s) = 1.96 TeV. The data cover jet transverse momenta from 37--380 GeV and absolute jet rapidities in the range 0.1--0.7.

The Z pT at $\sqrt{s} = 7$\;TeV is measured using electron and muon $Z$ decay channels. The dressed leptons definition uses photons clustered in a cone around the charged leptons, while the bare lepton definition uses the post-FSR charged leptons only in the $Z$ reconstruction. The data used in the bare leptons calculation are based on a forward application of a PHOTOS-based energy loss correction and are hence not quite model-independent.

Dijet azimuthal decorrelation measured by ATLAS at 7 TeV. Jets are anti- kt with $R=0.6$, $p_\perp>100$ GeV, $|\eta|<0.8$. The analysis is binned in leading jet $p_\perp$ bins. All data is fully corrected.

Measurement of jet shapes in inclusive jet production in pp collisions at 7 TeV based on 3pb$^-1$ of data. Jets are reconstructed in $|\eta| < 5$ using the anti-$k_\perp$ algorithm with $30 < pT < 600$ GeV and $|y| < 2.8$.

ATLAS measurement of track jet pT, multiplicity per jet, longitudinal fragmentation, transverse momentum, radius w.r.t jet axis distributions, with jets constructed from charged tracks with $pT > 300$ MeV, using the anti-$k_T$ jet algorithm with $R = 0.4, 0.6$.

Cross sections, in both the electron and muon decay modes of the W boson, are presented as a function of jet multiplicity and of the transverse momentum of the leading and next-to-leading jets in the event. Measurements are also presented of the ratio of cross sections for inclusive jet multiplicities. The results, based on an integrated luminosity of 1.3 pb-1, have been corrected for all known detector effects and are quoted in a limited and well-defined range of jet and lepton kinematics.

The underlying event measurements with the ATLAS detector at the LHC at the center of mass energies of 900 GeV and 7 TeV. The observables sensitive to the underlying event, i.e the charged particle density and charged pT sum, as well as their standard deviations and the average pT, are measured as functions of the leading track. A track pT cut of 500 MeV is applied for most observables, but the main profile plots are also shown for a lower track cut of 100 MeV, which includes much more of the soft cross-section. The angular distribution of the charged tracks with respect to the leading track is also studied, as are the correlation between mean transverse momentum and charged particle multiplicity, and the `plateau' height as a function of the leading track $|\eta|$.
