Search for the doubly charmed baryon Ξ+cc

LHCb Collaboration

Research output: Contribution to journalArticlepeer-review


A search for the doubly charmed baryon Ξ+cc in the decay mode Ξ+cc→Λ+cK−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/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.
