| BaBar | $2.65 \pm0.09 \pm0.08$ | 0.06 | Phys.Rev.D 85,112010 (2012) | Result extracted from Dalitz-plot analysis of $B^0 \to K_S^0 K^+ K^-$ decays. All charmonium resonances are vetoed, except for $\chi_{c0}$. The analysis also reports ${\cal{B}}( B^{0} \to K^0 K^+ K^- ) = (25.4 \pm 0.9 \pm 0.8) \times 10^{-6}$ excluding $\chi_{c0}$. |
