Abstract
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 $K^+K^-$ invariant mass. Combined with the results from our $CP$ asymmetry measurements in the $B_s \rightarrow J/\psi \phi$ decays, we conclude that the $B_s$ mass eigenstate that is almost $CP =+1$ is lighter and decays faster than the mass eigenstate that is almost $CP =-1$. This determines the sign of the decay width difference $\Delta\Gamma_s \equiv \Gamma_L -\Gamma_H$ to be positive. Our result also resolves the ambiguity in the past measurements of the $CP$ violating phase $\phi_s$ to be close to zero rather than $\pi$. These conclusions are in agreement with the Standard Model expectations.
