Search for the doubly charmed baryon Ξ[+ over cc]
A search for the doubly charmed baryon Ξ[+ over cc] in the decay mode Ξ[+ over cc] → Λ[+ over c]K[superscript −]π[superscript +] is performed with a data sample, corresponding to an integrated luminosity of 0.65 fb[superscript −1], of pp collisions recorded at a centre-of-mass energy of 7 TeV.

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