Research output: Contribution to journalArticleAcademicpeer-review


A search for the doubly charmed baryon Xi(+)(cc) in the decay mode Xi(+)(cc) -> Lambda(+)(c) K-pi(+) is performed with a data sample, corresponding to an integrated luminosity of 0.65 fb(-1), of p p collisions recorded at a centre-of-mass energy of 7TeV. No significant signal is found in the mass range 3300-3800MeV/c(2). Upper limits at the 95% confidence level on the ratio of the Xi(+)(cc) production cross-section times branching fraction to that of the Lambda(+)(c), R, are given as a function of the Xi(+)(cc) mass and lifetime. The largest upper limits range from R < 1.5x10(-2) for a lifetime of 100 fs to R < 3.9 x 10(-4) for a lifetime of 400 fs.
