Observation of $ψ(3686) \rightarrow e^{+}e^{-}χ_{cJ}$ and $χ_{cJ} \rightarrow e^{+}e^{-}J/ψ$

M. Ablikim, M. N. Achasov, X. C. Ai, O. Albayrak et autres

Using $4.479 \times 10^{8}$ $ψ(3686)$ events collected with the BESIII detector, we search for the decays $ψ(3686) \rightarrow e^{+}e^{-}χ_{c0,1,2}$ and $χ_{c0,1,2} \rightarrow e^{+}e^{-}J/ψ$. The decays $ψ(3686) \rightarrow e^{+}e^{-}χ_{c0,1,2}$ and $χ_{c0,1,2} \rightarrow e^{+}e^{-}J/ψ$ are observed for the first time. The measured branching fractions …

B[superscript 0] meson decays to ρ[superscript 0]K[superscript *0], f[subscript 0]K[superscript *0], and ρ[superscript -]K[superscript *+], including higher K[superscript *] resonances

Search for the rare decay B→Kνν

P. del Amo Sanchez, J. P. Lees, V. Poireau, Elisabetta Prencipe et autres

We present a search for the rare decays B⊃+→K⊃+νν̄ and B0→K0νν̄ using 459×106 BB̄ pairs collected with the BABAR detector at the SLAC National Accelerator Laboratory. Flavor-changing neutral-current decays such as these are forbidden at tree level but can occur through one-loop …
