Measurement of the t-channel single top-quark production cross section in pp collisions at $\sqrt{s}$ = 7 TeV with the ATLAS detector / ATLAS Collaboration
We report a measurement of the cross section of single top-quark production in the t-channel using 1.04 fb$^{-1}$ of pp collision data at $\sqrt{s}$ = 7 TeV recorded with the ATLAS detector at the LHC. Selected events feature one electron or muon, missing transverse momentum, and two or three jets, exactly one of them identified as originating from a b quark. [...]

Search for lepton flavour violation in the $e\mu$ continuum with the ATLAS detector in $\sqrt{s}$ = 7 TeV pp collisions at the LHC / ATLAS Collaboration
This paper presents a search for the t-channel exchange of an R-parity violating scalar top quark ($\tilde{t}$) in the $e^{\pm}\mu^{\pm}$ continuum using 2.1/fb of data collected by the ATLAS detector in $\sqrt{s}$ = 7 TeV pp collisions at the Large Hadron Collider. Data are found to be consistent with the expectation from the Standard Model backgrounds. [...]

Searches for TeV-scale Gravity Signatures in Final States with Leptons and Jets with the ATLAS Detector at $\sqrt{s}$ = 7 TeV / ATLAS Collaboration
The production of events with multiple high transverse momentum particles including charged leptons and jets is measured, using 1.04 fb-1 of proton-proton collision data recorded by the ATLAS detector during the first half of 2011 at $\sqrt{s}$ = 7 TeV. No excess beyond Standard Model expectations is observed, and upper limits on the fiducial cross sections for non-Standard Model production of these final states are set. [...]

Search for events with large missing transverse momentum, jets, and at least two tau leptons in 7 TeV proton-proton collision data with the ATLAS detector / ATLAS Collaboration
A search for events with large missing transverse momentum, jets, and at least two tau leptons has been performed using 2 fb^-1 of proton-proton collision data at $\sqrt{s}$ = 7 TeV recorded with the ATLAS detector at the Large Hadron Collider. No excess above the Standard Model background expectation is observed and a 95% CL visible cross section upper limit for new phenomena is set. [...]

Search for supersymmetry in pp collisions at $\sqrt{s}$ = 7 TeV in final states with missing transverse momentum and b-jets with the ATLAS detector / ATLAS Collaboration
The results of a search for supersymmetry in events with large missing transverse momentum and heavy flavour jets using an integrated luminosity corresponding to 2.05 fb-1 of pp collisions at $\sqrt{s}$ = 7 TeV recorded with the ATLAS detector at the Large Hadron Collider are reported. No significant excess is observed with respect to the prediction for Standard Model processes. [...]

Measurement of the top quark mass with the template method in the top antitop $\to$ lepton + jets channel using ATLAS data / ATLAS Collaboration
The top quark mass has been measured using the template method in the top antitop $\to$ lepton + jets channel based on data recorded in 2011 with the ATLAS detector at the LHC. The data were taken at a proton-proton centre-of-mass energy of $\sqrt{s}$ = 7 TeV and correspond to an integrated luminosity of 1.04/fb. [...]

Jet mass and substructure of inclusive jets in $\sqrt{s}$ = 7 TeV pp collisions with the ATLAS experiment / ATLAS Collaboration
Recent studies have highlighted the potential of jet substructure techniques to identify the hadronic decays of boosted heavy particles. These studies all rely upon the assumption that the internal substructure of jets generated by QCD radiation is well understood. [...]
