An unbinned likelihood fit for the measurement of $\phi_s$ in the decay $B_s \to J/\psi\phi$
The interference between $B^0_s$ decays to $J/\psi\phi$ with or without $B^0_s-\overline{B}^0_s$ oscillation gives rise to a CP violating phase $\phi_s$. In the Standard model, this phase is predicted to be $-2\beta_s$ = $-0.0368\pm0.0017$. New Physics could significantly modify this prediction. The...
