@stefanmeinel.bsky.socialObservation of the Ξb⁻→Ξ⁻μ⁺μ⁻ and study of the Ξb⁻→Ξ⁻ψ(2S) decays - The integrated value of B(Ξb⁻→Ξ⁻μ⁺μ⁻) is measured to be (118±24±7±38)×10⁻⁸. The ratio of the branching fractions of the Ξb⁻→Ξ⁻ψ(2S) and the Ξb⁻→Ξ⁻J/ψ decays is measured to be 0.491±0.041±0.019. arxiv.org/abs/2610.22452
