### Event details

The amount of CP asymmetry in the Standard Model is way too small to explain the total observed matter abundance in the universe. The LHCb detector is designed to search for indirect evidence of physics beyond the Standard Model in CP violation. The CP violating phase $\phi_s$ is very precisely predicted assuming the Standard Model. It arises in the interference between the direct decay of the Bs meson and via oscillation into its antiparticle to the same final state. In this talk, I will cover the experimental result of $\phi_s$ using Run 2 data of the golden decay mode Bs to J/psiPhi. Combining this result with previously conducted analyses will drive the experimental precision towards the theoretical prediction. A significant deviation could be a hint for yet unknown physics phenomena.
