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 7 TeV. 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 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 x 10^−2 for a lifetime of 100 fs to R < 3.9 x 10^−4 for a lifetime of 400 fs.
