  We present the energy spectra of the low lying doubly-charmed baryons using
lattice quantum chromodynamics. We precisely predict the ground state mass of
the charmed-strange Omega(cc) (1/2+) baryon to be 3712(11)(12) MeV which could
well be the next doubly-charmed baryon to be discovered at the LHCb experiment
at CERN. We also predict masses of other doubly-charmed strange baryons with
quantum numbers 3/2+, 1/2-, and 3/2-.
