Determination of 2$\beta_{s}$ in $B^{0}_s \to J/\psi K^{+} K^{-}$ Decays in the Presence of a $K^{+}K^{-}$ S-Wave Contribution
We present the complete differential decay rates for the process B_s -> J/psi K^+ K^- including S-wave and P-wave angular momentum states for the K^+ K^- meson pair. We examine the effect of an S-wave component on the determination of the CP violating phase 2beta_s. Data from the B-factories indi...
