Determination of the sign of the decay width difference in the $B^0_s$ system

The interference between the $K^+K^-$ S-wave and P-wave amplitudes in $B_s \rightarrow J/\psi K^+K^-$ decays with the $K^+K^-$ pairs in the region around the $\phi(1020)$ resonance is used to determine the variation of the difference of the strong phase between these amplitudes as a function of $K^+...
