Measurement of the $\bar{B}_s^0\to D_s^-D_s^+$ and $\bar{B}_s^0\to D^-D_s^+$ effective lifetimes / LHCb collaboration
The first measurement of the effective lifetime of the $\bar{B}_s^0$ meson in the decay $\bar{B}_s^0\to D_s^-D_s^+$ is reported using a proton-proton collision dataset, corresponding to an integrated luminosity of 3 fb$^{-1}$, collected by the LHCb experiment. The measured value of the $\bar{B}_s^0\to D_s^-D_s^+$ effective lifetime is $1.379\pm0.026\pm0.017$ ps, where the uncertainties are statistical and systematic, respectively. [...]

Studies of beauty baryon decays to $D^0 ph^-$ and $\Lambda_c^+ h^-$ final states / LHCb collaboration
Decays of beauty baryons to the $D^0 p h^-$ and $\Lambda_c^+ h^-$ final states (where $h$ indicates a pion or a kaon) are studied using a data sample of $pp$ collisions, corresponding to an integrated luminosity of 1.0 fb$^{-1}$, collected by the LHCb detector. The Cabibbo-suppressed decays $\Lambda_b^0\to D^0 p K^-$ and $\Lambda_b^0\to \Lambda_c^+ K^-$ are observed and their branching fractions are measured with respect to the decays $\Lambda_b^0\to D^0 p \pi^-$ and $\Lambda_b^0\to \Lambda_c^+ \pi^-$.

Search for CP violation in the decay $D^+ \to \pi^-\pi^+\pi^+$ / LHCb collaboration
A search for CP violation in the phase space of the decay $D^+\to\pi^-\pi^+\pi^+$ is reported using $pp$ collision data, corresponding to an integrated luminosity of 1.0 fb$^{-1}$, collected by the LHCb experiment at a centre-of-mass energy of 7 TeV. The Dalitz plot distributions for $3.1\times 10^6$ $D^+$ and $D^-$ candidates are compared with binned and unbinned model-independent techniques. [...]

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.

Measurement of $D^{0}-\bar{D}^0$ mixing parameters and search for CP violation using $D^{0} \to K^{+}\pi^{-}$ decays / LHCb collaboration
Measurements of charm mixing parameters from the decay-time-dependent ratio of $D^0 \to K^+ \pi^-$ to $D^0 \to K^- \pi^+$ rates and the charge-conjugate ratio are reported.
