φs = -0.041±0.025 rad (LHCb) φs = -0.055±0.021 rad (World) The LHCb collaboration has submitted for publication an updated measurement of the CP-violating phase φs in Bs0 meson decays. The precision measurement of φs is one of the most important goals of the LHCb experiment. In the wonderful world of quantum mechanics a Bs0 meson…
