Tagged time-dependent angular analysis of $B_s^0 \to J/\psi\phi$ decays at LHCb
The interference between $B_s^0$ decays to $J/\psi \phi$ either directly or via $B_s^0-\bar{B}_s^0$ oscillation gives rise to a $CP$ violating phase $\phi_s$. Using a sample of about $21,200$ $B_s^0\to J/\psi \phi$ events extracted from 1$fb^{-1}$ of $pp$ collisions collected during the 2011 LHC...
