ZunicaAbstract:
The first observation of the decay is reported with high significance using proton-proton collision data, corresponding to an integrated luminosity of , collected with the LHCb detector at a center-of-mass energy of 13 TeV. A yield of decays is obtained, where the uncertainty is statistical only. A branching fraction of is measured, where the uncertainty includes statistical and systematic sources. No evidence of resonant structures is found in the dimuon invariant-mass distribution. All results are compatible with standard model expectations. This represents the rarest decay of a baryon ever observed.Observation of ψ (3686) → Ξ − K S 0 Ω ¯ + + c.c

Using a sample of (2.712 ± 0.014) × 109ψ(3686) events collected with the BESIII detector at the electron positron collider BEPCII, the decay ψ(3686) → Ξ−KS0Ω¯+ + c.c. is observed for the first time, which has a significance of 5.9 standard deviations. The branching fraction of this decay is measured to be (2.91 ± 0.47 ± 0.33) × 10−6, where the first and second uncertainties are statistical and systematic, respectively. The ratio between Bψ3686→Ξ−KS0Ω¯++c.c and Bψ3686→Ω−K+Ξ¯0+c.c is determined to be 1.05 ± 0.23 ± 0.14, which deviates from the isospin symmetry conservation predicted value of 0.5 by 2.1σ.Measurement of the branching fractions of doubly Cabibbo-suppressed D decays
