Measurement of the $B_s^0$ mixing phase using $B_s^0 → ϕϕ$ / Needham, M (Edinburgh U.)
Using 3 fb−1 of collision data collected by the LHCb collaboration in proton-proton collisions the Bs0 mixing phase, ϕs in the Bs0→ϕϕ decay mode is determined to be ϕs=−0.17±0.15(stat)±0.03(syst) . This is consistent with the Standard Model expectation that CP violation in this channel is small..

Measurement of the weak mixing phase $\phi_s$ through time-dependent $CP$ violation in $B_s^0 \rightarrow J/\psi\phi$ decay in ATLAS / Jakoubek, Tomas (Institute of Physics of the Czech Academy of Sciences) /ATLAS Collaboration
In the Standard Model of particle physics, $CP$ violation arises due to a single complex phase in the Cabibbo-Kobayashi-Maskawa (CKM) quark mixing matrix. Testing the validity of the CKM mechanism as the only source of $CP$ violation is one of the major experimental challenges in particle physics today. [...]

$CP$ violation in the B system at LHCb / Saborido Silva, J J (Santiago de Compostela U.)
A selection of recent LHCb results on $CP$ violation in the $B$ system is presented. These include direct $CP$ violation measurements in $B^0 \to \phi K^*(892)^0$, $B_{(s)}^0 \to K^\pm\pi^\pm$, $B^\pm \to K^\pm \pi^+\pi^-$, $B^\pm \to K^\pm K^+K^-$ and $B^\pm \to \phi K^\pm$ decays; time-dependent $CP$ violation measurements in $B_s^0 \to K^+K^-$ and $B^0 \to \pi^+\pi^-$ decays; determination of the flavour-specific $CP$-violating asymmetry $a_{sl}^s$ in $B_s^0$ decays; and study of the mixing-induced $CP$ violation in $B_s^0 \to J/\psi K^+K^-$ and $B_s^0 \to J/\psi \pi^+\pi^-$ decays..

CP Violation in the $B$ system with the LHCb experiment / Martens, Aurélien (Paris U., VI-VII)
During 2011, LHCb has collected an integrated luminosity of 1.1 fb$^{-1}$, giving rise to a large variety of measurements. Amongst these, measurements of $CP$ violation in $B$ decays play a central role. [...]
