Measurement of $D^{*\pm}$, $D^\pm$ and $D_s^\pm$ meson production cross sections in $pp$ collisions at $\sqrt{s}=7$ TeV with the ATLAS detector / ATLAS Collaboration
The production of $D^{*\pm}$, $D^\pm$ and $D_s^\pm$ charmed mesons has been measured with the ATLAS detector in $pp$ collisions at $\sqrt{s}=7$ TeV at the LHC, using data corresponding to an integrated luminosity of $280\,$nb$^{-1}$. The charmed mesons have been reconstructed in the range of transverse momentum $3.5<p_{\rm T}(D)<100$ GeV and pseudorapidity $|\eta(D)|<2.1$. [...]

Performance of $b$-Jet Identification in the ATLAS Experiment / ATLAS Collaboration
The identification of jets containing $b$ hadrons is important for the physics programme of the ATLAS experiment at the Large Hadron Collider. Several algorithms to identify jets containing $b$ hadrons are described, ranging from those based on the reconstruction of an inclusive secondary vertex or the presence of tracks with large impact parameters to combined tagging algorithms making use of multi-variate discriminants.

Performance of pile-up mitigation techniques for jets in $pp$ collisions at $\sqrt{s} = 8$ TeV using the ATLAS detector / ATLAS Collaboration
The large rate of multiple simultaneous proton--proton interactions, or pile-up, generated by the Large Hadron Collider in Run 1 required the development of many new techniques to mitigate the adverse effects of these conditions. This paper describes the methods employed in the ATLAS experiment to correct for the impact of pile-up on jet energy and jet shapes, and for the presence of spurious additional jets, with a primary focus on the large 20.3 fb$^{-1}$ data sample collected at a centre-of-mass energy of $\sqrt{s} = 8$ TeV.

Study of the $B_c^+ \to J/\psi D_s^+$ and $B_c^+ \to J/\psi D_s^{*+}$ decays with the ATLAS detector / ATLAS Collaboration
The decays $B_c^+ \to J/\psi D_s^+$ and $B_c^+ \to J/\psi D_s^{*+}$ are studied with the ATLAS detector at the LHC using a dataset corresponding to integrated luminosities of 4.9 fb$^{-1}$ and 20.6 fb$^{-1}$ of $pp$ collisions collected at centre-of-mass energies $\sqrt{s} = 7$ TeV and 8 TeV, respectively. Signal candidates are identified through $J/\psi\to\mu^+\mu^-$ and $D_s^{(*)+}\to\phi\pi^+(\gamma/\pi^0)$ decays. [...]

Flavour tagged time dependent angular analysis of the $B_s \rightarrow J/\psi \phi$ decay and extraction of $\Delta\Gamma$ and the weak phase $\phi_s$ in ATLAS / ATLAS Collaboration
A measurement of the $B_s \rightarrow J/\psi \phi$ decay parameters, updated to include flavour tagging is reported using $4.9 fb^{-1}$ of integrated luminosity collected by the ATLAS detector from $\sqrt{s}= 7$TeV $pp$ collisions recorded in 2011 at the LHC. The values measured for the physical parameters are: \begin{eqnarray*} \phi_s & = & 0.12 \pm 0.25(stat.)\pm 0.05(syst.)rad \\ \Delta\Gamma & = & 0.053 \pm 0.021(stat.) 0.010(syst.)ps^{-1} \\ \Gamma_s & = & 0.677 \pm 0.007 (stat.)\pm 0.004 (syst.)ps^{-1}\\ |A_{\parallel}(0)|^2 & = & 0.220 \pm 0.008 (stat.)\pm 0.009(syst.)\\ |A_{0}(0)|^2 & = & 0.529 \pm 0.006 (stat.)\pm 0.012(syst.)\\ \delta_\perp & = & 3.89 \pm 0.47(stat.) \pm 0.11(syst.)rad \end{eqnarray*} where the parameter $\Delta\Gamma$ is constrained to be positive.

Jet energy measurement and its systematic uncertainty in proton-proton collisions at $\sqrt{s}$=7 TeV with the ATLAS detector / ATLAS Collaboration
The jet energy scale (JES) and its systematic uncertainty are determined for jets measured with the ATLAS detector using proton-proton collision data with a centre-of-mass energy of $\sqrt{s}=7$ TeV corresponding to an integrated luminosity of 4.7 fb$^{-1}$. Jets are reconstructed from energy deposits forming topological clusters of calorimeter cells using the anti-k$_t$ algorithm with distance parameters $R=0.4$ or $R=0.6$, and are calibrated using MC simulations.

Measurement of $\chi_{c1}$ and $\chi_{c2}$ production with $\sqrt{s}=7$ TeV $pp$ collisions at ATLAS / ATLAS Collaboration
The prompt and non-prompt production cross-sections for the $\chi_{c1}$ and $\chi_{c2}$ charmonium states are measured in $pp$ collisions at $\sqrt{s}=7$ TeV with the ATLAS detector at the LHC using 4.5 fb-1 of integrated luminosity. The $\chi_{c}$ states are reconstructed through the radiative decay $\chi_{c}\rightarrow J/\psi\,\gamma$ (with $J/\psi\rightarrow\mu^{+}\mu^{-}$) where photons are reconstructed from $\gamma\rightarrow e^{+}e^{-}$ conversions.

Muon reconstruction efficiency and momentum resolution of the ATLAS experiment in proton–proton collisions at $\sqrt{s}=7$ TeV in 2010 / ATLAS Collaboration
This paper presents a study of the performance of the muon reconstruction in the analysis of proton--proton collisions at $\sqrt{s}=7$ TeV at the LHC, recorded by the ATLAS detector in 2010. This performance is described in terms of reconstruction and isolation efficiencies and momentum resolutions for different classes of reconstructed muons. [...]

Search for supersymmetry at $\sqrt{s}=8$ TeV in final states with jets and two same-sign leptons or three leptons with the ATLAS detector / ATLAS Collaboration
A search for strongly produced supersymmetric particles is conducted using signatures involving multiple energetic jets and either two isolated leptons ($e$ or $\mu$) with the same electric charge, or at least three isolated leptons. The search also utilises jets originating from $b$-quarks, missing transverse momentum and other observables to extend its sensitivity. [...]

Measurement of the low-mass Drell--Yan differential cross section at √s = 7 TeV using the ATLAS detector / ATLAS Collaboration
The differential cross section for the process $Z/\gamma^*\rightarrow \ell\ell$ ($\ell=e,\mu$) as a function of dilepton invariant mass is measured in $pp$ collisions at $\sqrt{s}=7$ TeV at the LHC using the ATLAS detector. The measurement is performed in the $e$ and $\mu$ channels for invariant masses between $26$ GeV and $66$ GeV using an integrated luminosity of $1.6$ fb$^{-1}$ collected in 2011 and these measurements are combined.
