Measurement of the charge asymmetry in $B^{\pm}\rightarrow \phi K^{\pm}$ and search for $B^{\pm}\rightarrow \phi \pi^{\pm}$ decays / LHCb collaboration
The CP-violating charge asymmetry in $B^{\pm}\rightarrow \phi K^{\pm}$ decays is measured in a sample of $pp$ collisions at 7 TeV centre-of-mass energy, corresponding to an integrated luminosity of 1.0 fb$^{-1}$ collected by the LHCb experiment. The result is $\mathcal{A}_{CP}(B^{\pm}\rightarrow \phi K^{\pm}) = \rm 0.022\pm 0.021 \pm 0.009$, where the first uncertainty is statistical and the second systematic. [...]

Production of $J/\psi$ and $\Upsilon$ mesons in $pp$ collisions at $\sqrt{s}$ = 8 TeV / LHCb Collaboration
The production of $J/\psi$ and $\Upsilon$ mesons in $pp$ collisions at $\sqrt{s}$ = 8 TeV is studied with the LHCb detector. The $J/\psi$ and $\Upsilon$ mesons are reconstructed in the $\mu^+ \mu^-$ decay mode and the signal yields are determined to fit to the $\mu^+ \mu^-$ invariant mass distributions. [...]

Measurement of the polarization amplitudes in $B^0 \to J/\psi K^{*}(892)^0$ decays / LHCb collaboration
An analysis of the decay $B^0 \to J/\psi K^{*}(892)^0$ is presented using data, corresponding to an integrated luminosity of 1.0 fb$^{-1}$, collected in $pp$ collisions at a centre-of-mass energy of 7TeV with the LHCb detector. The polarisation amplitudes and the corresponding phases are measured to be \[ \begin{array}{cclllllll} |A_{\parallel}|^2 &\;=\; & 0.227 &\pm & 0.004 & \text{(stat.)} &\pm & 0.011 & \text{(syst.)}, \\ |A_{\perp}|^2 &\;=\; & 0.201 &\pm & 0.004 & \text{(stat.)} &\pm & 0.008&\text{(syst.)},\\ \delta_{\parallel}\; \text{[rad]} &\;=\; & -2.94 &\pm & 0.02 &\text{(stat.)} &\pm &0.03&\text{(syst.)},\\ \delta_{\perp}\; \text{[rad]} &\;=\; & \phantom{-}2.94 &\pm & 0.02 &\text{(stat.)} &\pm &0.02&\text{(syst.)}.\\ \end{array} \] Comparing $B^0\to J/\psi K^{*}(892){^0}$ and $\overline{B}^0\to J/\psi \overline K^{*}(892){^0}$ decays, no evidence for direct CP violation is found..
