The SELEX experiment (E781) at Fermilab has candidates for high mass states decaying to Lambdac+ K- pi+ and Lambdac+ K- pi+ pi+, Cabibbo-allowed decay modes of doubly-charmed baryons Xicc+ and Xicc++. The masses are consistent with theoretical considerations, but the spectroscopy is surprising. Limited lifetime information suggests that tauXicc++ ∼ tauXicc+.
