Abstract
Universal properties of mass-imbalanced three-body systems in 2D are
studied using zero-range interactions in momentum space. The dependence
of the three-particle binding energy on the parameters (masses and
two-body energies) is highly non-trivial even in the simplest case of
two identical particles and a distinct one. This dependence is
parametrized for ground and excited states in terms of supercircles
functions in the most general case of three distinguishable particles.
