Abstract

A search for the doubly charmed baryon Ξ_cc⁺ in the decay mode Ξ_cc⁺ → Λ_c ⁺K^-π⁺ is performed with a data sample, corresponding to an integrated luminosity of 0.65 fb^-1, of pp collisions recorded at a centre-of-mass energy of 7TeV. No significant signal is found in the mass range 3300-3800 MeV/c². Upper limits at the 95% confidence level on the ratio of the Ξ_cc⁺ production cross-section times branching fraction to that of the Λ_c ⁺, R, are given as a function of the Ξ_cc⁺ mass and lifetime. The largest upper limits range from R < 1.5 × 10^-2 for a lifetime of 100 fs to R < 3.9 × 10^-4 for a lifetime of 400 fs. Copyright CERN.
