Measurement of the weak mixing phase $\phi_s$ through time-dependent $CP$ violation in $B_s^0 \to J/\psi\phi$ decay in ATLAS
An updated measurement of time-dependent $CP$ asymmetry parameters in $B_s^0 \to J/\psi(\mu^+\mu^-)\phi(K^+K^-)$ decays using 80.5 fb$^{-1}$ of integrated luminosity collected with the ATLAS detector from 13~TeV $pp$ collisions at the LHC is presented. In the Standard Model, $CP$ violation arises du...
