Аннотация

A search for the Ξcc++ baryon through the Ξcc++→ D⁺pK⁻π⁺ decay is performed with a data sample corresponding to an integrated luminosity of 1.7 fb⁻¹ recorded by the LHCb experiment in pp collisions at a centre-of-mass energy of 13 TeV. No significant signal is observed in the mass range from the kinematic threshold of the decay to 3800 MeV/c². An upper limit is set on the ratio of branching fractions ℛ=ℬ(Ξcc++→D+pK−π+)ℬ(Ξcc++→Λc+K−π+π+) with ℛ < 1.7 (2.1) × 10⁻² at the 90% (95%) confidence level at the known mass of the Ξcc++ state.
