Query: Lower bound to the mass of a relativistic three-boson system in the
  light-cone   The lower bound masses of the ground-state relativistic three-boson system in
1+1, 2+1 and 3+1 space-time dimensions are obtained. We have considered a
reduction of the ladder Bethe-Salpeter equation to the light-front in a model
with renormalized two-body contact interaction. The lower bounds are deduced
with the constraint of reality of the two-boson subsystem mass. It is verified
that, in some cases, the lower bound approaches the ground state binding
energy. The corresponding non-relativistic limits are also verified.
