Beschreibungen/Notizen

• A search for the doubly charmed baryon Ξ c c + is performed through its decay to the Λ c + K − π + final state, using proton-proton collision data collected with the LHCb detector at centre-of-mass energies of 7, 8 and 13 TeV. The data correspond to a total integrated luminosity of 9 fb −1 . No significant signal is observed in the mass range from 3.4 to 3.8 GeV/ c 2 . Upper limits are set at 95% credibility level on the ratio of the Ξ c c + production cross-section times the branching fraction to that of Λ c + and Ξ c c + + baryons. The limits are determined as functions of the Ξ c c + mass for different lifetime hypotheses, in the rapidity range from 2.0 to 4.5 and the transverse momentum range from 4 to 15 GeV/ c .
