| BaBar | $3.46 \pm0.06 \pm0.09$ | 0.44 | Phys.Rev.D 85,112010 (2012) | Result extracted from Dalitz-plot analysis of $B^+ \to K^+ K^+ K^-$ decays. All charmonium resonances are vetoed, except for $\chi_{c0}$. The analysis also reports ${\cal{B}}( B^{+} \to K^+ K^+ K^- ) = (33.4 \pm 0.5 \pm 0.9) \times 10^{-6}$ excluding $\chi_{c0}$. |
