Search for a supersymmetric partner to the top quark in final states with jets and missing transverse momentum at $\sqrt{s}$ = 7 TeV with the ATLAS detector / ATLAS Collaboration
A search for direct pair production of supersymmetric top squarks (stop_1) is presented, assuming the stop_1 decays into a top quark and the lightest supersymmetric particle, neutralino_1, and that both top quarks decay to purely hadronic final states. A total of 16 (4) events are observed compared to a predicted Standard Model background of $13.5^{+3.7}_{-3.6} (4.4^{+1.7}_{-1.3})$ events in two signal regions based on $\int$(Ldt) = 4.7 fb$^{-1}$ of pp collision data taken at $\sqrt{s}$ = 7 TeV with the ATLAS detector at the LHC.

Time-dependent angular analysis of the decay $B_s^0 \to J/\psi \phi$ and extraction of $\Delta \Gamma_s$ and the CP-violating weak phase $\phi_s$ by ATLAS / ATLAS Collaboration
A measurement of $B_s^0 \to J/\psi \phi$ decay parameters, including the CP-violating weak phase $\phi_s$ and the decay width difference $\Delta \Gamma_s$ is reported, using 4.9 fb$^{-1}$ of integrated luminosity collected in 2011 by the ATLAS detector from LHC pp collisions at a centre-of-mass energy $\sqrt{s}$ = 7 TeV. The mean decay width $\Gamma_s$ and the transversity amplitudes $|A_0(0)|^2$ and $|A_{||}(0)|^2$ are also measured. [...]

Underlying event characteristics and their dependence on jet size of charged-particle jet events in pp collisions at $\sqrt{s}$ = 7 TeV with the ATLAS detector / ATLAS Collaboration
Distributions sensitive to the underlying event are studied in events containing one or more charged-particle jets produced in pp collisions at $\sqrt{s}$ = 7 TeV with the ATLAS detector at the Large Hadron Collider (LHC). These measurements reflect 800 inverse microbarns of data taken during 2010. [...]

The measurement of several event shape variables is presented in minimum bias pp collisions at a center-of-mass energy of 7 TeV using the ATLAS detector at the LHC. The observables studied are the transverse thrust, thrust minor and transverse sphericity, each defined using the momenta perpendicular to the beam direction of the final state charged particles.

Search for magnetic monopoles in $\sqrt{s}$ = 7 TeV pp collisions with the ATLAS detector / ATLAS Collaboration
This Letter presents a search for magnetic monopoles with the ATLAS detector at the CERN Large Hadron Collider using an integrated luminosity of 2.0 fb$^{-1}$ of pp collisions recorded at a center-of-mass energy of $\sqrt{s}$ = 7 TeV. No event is found in the signal region, leading to an upper limit on the production cross section at 95% confidence level of 2 fb for Dirac magnetic monopoles with the minimum unit magnetic charge and with mass between 200 GeV and 1500 GeV.
