Abstract
The doubly charmed baryon decay is observed for the first time, with a statistical significance of , confirming a recent observation of the baryon in the final state. The data sample used corresponds to an integrated luminosity of , collected by the LHCb experiment in collisions at a center-of-mass energy of 13 TeV. The mass is measured to be and is consistent with the previous result. The ratio of branching fractions between the decay modes is measured to be .
