  Baryon-baryon bound states in the strangeness S=-2, S=-3, and S=-4 sectors
are considered. In particular, the dependence of the corresponding binding
energies on the quark mass (or equivalently the pion mass) is explored in the
framework of chiral effective field theory, in order to connect with current
lattice QCD calculations. For a bound state in the Xi-Xi 1S0 channel, predicted
by our leading-order effective field theory interaction, binding energies are
inferred that are roughly in line with a recent lattice QCD result at meson and
baryon masses that correspond to those in the lattice simulation. With regard
to the so-called H-dibaryon it is shown that the SU(3) breaking effects induced
by the differences of the pertinent two-baryon thresholds (Lambda-Lambda, Xi-N,
Sigma-Sigma) have a very pronounced impact on its binding energy. A bound
H-dibaryon as found in two lattice calculations could be shifted above the
Lambda-Lambda or even above the Xi-N threshold for physical masses of the
involved baryons.
