Baryons made of three heavy quarks become weakly coupled, when all the quarksare sufficiently heavy such that the typical momentum transfer is much largerthan Lambda_QCD. We use variational method to estimate masses of thelowest-lying bcc, ccc, bbb and bbc states by assuming they are Coulomb boundstates. Our predictions for these states are systematically lower than thosemade long ago by Bjorken.Comment: 31 pages, 5 figure
