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. [...]

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. [...]

Measurement of the production cross-section of prompt J/$\psi$ mesons in association with a W± boson in pp collisions at √s = 7 TeV with the ATLAS detector / ATLAS Collaboration
The process $pp \to W^{\pm} J/\psi$ provides a powerful probe of the production mechanism of charmonium in hadronic collisions, and is also sensitive to multiple parton interactions in the colliding protons. Using the 2011 ATLAS dataset of 4.5 fb-1 of $\sqrt{s}$ = 7 TeV pp collisions at the LHC, the first observation is made of the production of $W^{\pm}$ + prompt $J/\psi$ events in hadronic collisions, using $W^{\pm} \to \mu\nu_{\mu}$ and $J/\psi \to \mu^+\mu^-$.

Measurements of indirect CP asymmetries in $D^0\to K^-K^+$ and $D^0\to\pi^-\pi^+$ decays / LHCb collaboration
A study of indirect CP violation in $D^0$ mesons through the determination of the parameter $A_\Gamma$ is presented using a data sample of $pp$ collisions, corresponding to an integrated luminosity of 1.0 fb$^{-1}$, collected with the LHCb detector and recorded at the centre-of-mass energy of 7 TeV at the LHC. The parameter $A_\Gamma$ is the asymmetry of the effective lifetimes measured in decays of $D^0$ and $\overline{D}^0$ mesons to the CP eigenstates $K^-K^+$ and $\pi^-\pi^+$. [...]

Measurement of CP violation in the phase space of $B^{\pm} \rightarrow K^{+} K^{-} \pi^{\pm}$ and $B^{\pm} \rightarrow \pi^{+} \pi^{-} \pi^{\pm}$ decays / LHCb collaboration
The charmless decays $B^{\pm} \rightarrow K^{+}K^{-}\pi^{\pm}$ and $B^{\pm} \rightarrow \pi^{+}\pi^{-}\pi^{\pm}$ are reconstructed in a data set, corresponding to an integrated luminosity of 1.0 fb$^{-1}$ of pp collisions at a center-of-mass energy of 7 TeV, collected by LHCb in 2011. The inclusive charge asymmetries of these modes are measured to be $A_{CP}(B^{\pm} \rightarrow K^{+}K^{-}\pi^{\pm}) =-0.141 \pm 0.040 (stat) \pm 0.018 (syst) \pm 0.007 (J/\psi K^{\pm})$ and $A_{CP}(B^{\pm} \rightarrow \pi^{+}\pi^{-}\pi^{\pm}) = 0.117 \pm 0.021 (stat) \pm 0.009 (syst) \pm 0.007 (J/\psi K^{\pm})$, where the third uncertainty is due to the CP asymmetry of the $B^{\pm} \rightarrow J/\psi K^{\pm}$ reference mode.

Search for the decay $D^0\to\pi^+\pi^-\mu^+\mu^-$ / LHCb collaboration
A search for the $D^0\to \pi^+\pi^-\mu^+\mu^-$ decay, where the muon pair does not originate from a resonance, is performed using proton-proton collision data corresponding to an integrated luminosity of $1.0\mathrm{fb}^{-1}$ recorded by the LHCb experiment at a centre-of-mass energy of $7\mathrm{TeV}$. No signal is observed and an upper limit on the relative branching fraction with respect to the resonant decay mode $D^0\to \pi^+\pi^-\phi(\to\mu^+\mu^-)$, under the assumption of a phase-space model, is found to be \begin{align} \mathcal{B}(D^0\to \pi^+\pi^-\mu^+\mu^-)/\mathcal{B}(D^0\to \pi^+\pi^-\phi(\to\mu^+\mu^-)) < 0.96\\ \end{align} at the $90\%$ confidence level.

Decays of $\bar{B}^0_(s)$ and $\bar{B}^0$ mesons into $J/\psi \pi^+\pi^-\pi^+\pi^-$ final states, produced in $pp$ collisions at the LHC, are investigated using data corresponding to an integrated luminosity of 3 fb$^{-1}$ collected with the LHCb detector. $\bar{B}^0_{(s)}\to J/\psi f_1(1285)$ decays are seen for the first time, and the branching fractions are measured.
