Abstract

A search for the doubly charmed baryon Ξcc + in the decay mode Ξcc + → Λc +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 Ξcc + production cross-section times branching fraction to that of the Λc +, R, are given as a function of the Ξcc + 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.
