Query: Phenomenological view on baryon-baryon potentials from lattice QCD
  simulations   A qualitative discussion on the range of the potentials as they result from
the phenomenological meson-exchange picture and from lattice simulations by the
HAL QCD Collaboration is presented. For the former pion- and/or $\eta$-meson
exchange are considered together with the scalar-isoscalar component of
correlated $\pi\pi /K \bar K$ exchange. It is observed that the intuitive
expectation for the behavior of the baryon-baryon potentials for large
separations, associated with the exchange of one and/or two pions, does not
always match with the potentials extracted from the lattice simulations. Only
in cases where pion exchange provides the longest ranged contribution, like in
the $\Xi N$ system, a reasonable qualitative agreement between the
phenomenological and the lattice QCD potentials is found for baryon-baryon
separations of $r \gtrsim 1$ fm. For the $\Omega N$ and $\Omega\Omega$
interactions where isospin conservation rules out one-pion exchange a large
mismatch is observed, with the potentials by the HAL QCD Collaboration being
much longer ranged and much stronger at large distances as compared to the
phenomenological expectation. This casts some doubts on the applicability of
using these potentials in few- or many-body systems.
