The differential production cross section of the $\phi$(1020) meson in $\sqrt{s}$ = 7 TeV pp collisions measured with the ATLAS Detector / ATLAS Collaboration
A measurement is presented of the $\phi ➝ K^+K^−$ production cross section at √s = 7 TeV using pp collision data corresponding to an integrated luminosity of 383 μb$^{−1}$ collected with the ATLAS experiment at the LHC. Selection of $\phi$(1020) mesons is based on the identification of charged kaons by their energy loss in the pixel detector. [...]

Search for resonant diboson production in the $WW/WZ \to l\nu jj$ decay channels with the ATLAS detector at $\sqrt{s}$ = 7 TeV / ATLAS Collaboration
A search for resonant diboson production using a data sample corresponding to 4.7 fb$^{-1}$ of integrated luminosity collected by the ATLAS experiment at the Large Hadron Collider in pp collisions at $\sqrt{s}$ = 7 TeV is presented. The search for a narrow resonance in the WW or WZ mass distribution is conducted in a final state with an electron or a muon, missing transverse energy and at least two jets. [...]

Measurement of the inclusive jet cross-section in pp collisions at $\sqrt{s}$=2.76 TeV and comparison to the inclusive jet cross-section at $\sqrt{s}$=7 TeV using the ATLAS detector / ATLAS Collaboration
The inclusive jet cross-section has been measured in proton-proton collisions at √s = 2.76 TeV in a dataset corresponding to an integrated luminosity of 0.20 pb−1 collected with the ATLAS detector at the Large Hadron Collider in 2011. Jets are identified using the anti-kt algorithm with two radius parameters of 0.4 and 0.6. [...]

Search for third generation scalar leptoquarks in pp collisions at $\sqrt{s}$ = 7 TeV with the ATLAS detector / ATLAS Collaboration
A search for pair-produced third generation scalar leptoquarks is presented, using proton–proton collisions at $\sqrt{s}$ = 7 TeV at the LHC. The data were recorded with the ATLAS detector and correspond to an integrated luminosity of 4.7 fb$^{-1}$. [...]

Characterisation and mitigation of beam-induced backgrounds observed in the ATLAS detector during the 2011 proton-proton run / ATLAS Collaboration
This paper presents a summary of beam-induced backgrounds observed in the ATLAS detector and discusses methods to tag and remove background contaminated events in data. Trigger-rate based monitoring of beam-related backgrounds is presented. [...]

Improved luminosity determination in pp collisions at $\sqrt{s}$ = 7 TeV using the ATLAS detector at the LHC / ATLAS Collaboration
The luminosity calibration for the ATLAS detector at the LHC during pp collisions at $\sqrt{s}$ = 7 TeV in 2010 and 2011 is presented. Evaluation of the luminosity scale is performed using several luminosity-sensitive detectors, and comparisons are made of the long-term stability and accuracy of this calibration applied to the pp collisions at $\sqrt{s}$ = 7 TeV.

A Particle Consistent with the Higgs Boson Observed with the ATLAS Detector at the Large Hadron Collider / ATLAS Collaboration
Nearly 50 years ago, theoretical physicists proposed that a field permeates the universe and gives energy to the vacuum. This field was required to explain why some, but not all, fundamental particles have mass. [...]

Search for long-lived, multi-charged particles in pp collisions at $\sqrt{s}$=7 TeV using the ATLAS detector / ATLAS Collaboration
A search for highly ionising, penetrating particles with electric charges from |q| = 2e to 6e is performed using the ATLAS detector at the CERN Large Hadron Collider. Proton-proton collision data taken at $\sqrt{s}$=7 TeV during the 2011 running period, corresponding to an integrated luminosity of 4.4 fb$^{-1}$, are analysed. [...]

Search for charged Higgs bosons through the violation of lepton universality in $t\bar{t}$ events using pp collision data at $\sqrt{s}$ = 7 TeV with the ATLAS experiment / ATLAS Collaboration
In several extensions of the Standard Model, the top quark can decay into a bottom quark and a light charged Higgs boson $H^+, t \to bH^+$, in addition to the Standard Model decay $t \to bW$. Since W bosons decay to the three lepton generations equally, while $H^+$ may predominantly decay into $\tau\nu$, charged Higgs bosons can be searched for using the violation of lepton universality in top quark decays.
