Resumen

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/c 2. 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.
