  We provide a novel procedure to obtain complex PT-symmetric multi-particle
Calogero systems. Instead of extending or deforming real Calogero systems, we
explore here the possibilities for complex systems to arise from real nonlinear
field equations. We exemplify this procedure for the Boussinesq equation and
demonstrate how singularities in real valued wave solutions can be interpreted
as N complex particles scattering amongst each other. We analyze this
phenomenon in more detail for the two and three particle case. Particular
attention is paid to the implemention of PT-symmetry for the complex multi
particle systems. New complex PT-symmetric Calogero systems together with their
classical solutions are derived.
