Measurement of the $B_s^0$ mixing phase using $B_s^0 → ϕϕ$

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....
