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(Ξ++cc→D+pK−π+)B(Ξ++cc→Λ+cK−π+π+) with ℛ < 1.7 (2.1) × 10−2 at the 90% (95%) confidence level at the known mass of the Ξ++cc state.20 p.application/pdfengcc-by (c) LHCb Collaboration et al., 2019http://creativecommons.org/licenses/by/3.0/esCol·lisions (Física)BarionsCollisions (Physics)Baryonsinfo:eu-repo/semantics/article6963372020-05-22info:eu-repo/semantics/openAccess
