Measurement of the differential cross-sections of inclusive, prompt and non-prompt $J/\psi$ production in proton-proton collisions at $\sqrt{s}$ = 7 TeV / ATLAS Collaboration
The inclusive $J/\psi$ production cross-section and fraction of $J/\psi$ mesons produced in B-hadron decays are measured in proton-proton collisions at $\sqrt{s}$ = 7 TeV with the ATLAS detector at the LHC, as a function of the transverse momentum and rapidity of the $J/\psi$, using 2.3 pb.1 of integrated luminosity. The cross-section is measured from a minimum pT of 1 GeV to a maximum of 70 GeV and for rapidities within |y| < 2.4 giving the widest reach of any measurement of $J/\psi$ production to date. [...]

A search for new physics in dijet mass and angular distributions in pp collisions at √s = 7 TeV measured with the ATLAS detector / ATLAS Collaboration
A search for new interactions and resonances produced in LHC proton-proton (pp) collisions at a centre-of-mass energy !s = 7 TeV has been performed with the ATLAS detector. Using a dataset with an integrated luminosity of 36 pb−1, dijet mass and angular distributions have been measured up to dijet masses of " 3.5 TeV and found to be in good agreement with Standard Model predictions.

Search for Stable Hadronising Squarks and Gluinos at the ATLAS Experiment at the LHC / ATLAS Collaboration
Hitherto unobserved long-lived massive particles with electric and/or colour charge are predicted by a range of theories which extend the Standard Model. In this paper a search is performed at the ATLAS experiment for slow-moving charged particles produced in proton-proton collisions at 7 TeV centre-of-mass energy at the LHC, using a data-set corresponding to an integrated luminosity of 34 pb-1.

Measurements of underlying-event properties using neutral and charged particles in pp collisions at $\sqrt{s}$ = 900 GeV and $\sqrt{s}$ = 7 TeV with the ATLAS detector at the LHC / ATLAS Collaboration
We present first measurements of charged and neutral particle-flow correlations in pp collisions using the ATLAS calorimeters. Data were collected in 2009 and 2010 at centre-of-mass energies of 900 GeV and 7 TeV. [...]

Search for high-mass states with one lepton plus missing transverse momentum in proton-proton collisions at √s = 7 TeV with the ATLAS detector / ATLAS Collaboration
The ATLAS detector is used to search for high-mass states, such as heavy charged gauge bosons (W′, W∗), decaying to a charged lepton (electron or muon) and a neutrino. Results are presented based on the analysis of pp collisions at a center-of-mass energy of 7 TeV corresponding to an integrated luminosity of 36 pb−1. [...]

Measurement of Dijet Azimuthal Decorrelations in pp Collisions at √s = 7 TeV / ATLAS Collaboration
Azimuthal decorrelations between the two central jets with the largest transverse momenta are sensitive to the dynamics of events with multiple jets. We present a measurement of the normalized differential cross section based on the full dataset (L dt = 36 pb−1) acquired by the ATLAS detector during the 2010 √s = 7 TeV proton-proton run of the LHC [...]

Measurements of luminosity obtained using the ATLAS detector during early running of the Large Hadron Collider (LHC) at sqrt(s) = 7 TeV are presented.
