  We solved analytically the three-body mass-imbalanced problem embedded in D
dimensions for zero-range resonantly interacting particles. We derived the
negative energy eigenstates of the three-body Schrodinger equation by imposing
the Bethe-Peierls boundary conditions in D-dimensions for zero-energy two-body
bound states. The solution retrieves the Efimov-like discrete scaling factor
dependence with dimension. The analytical form of the mass-imbalanced
three-body bound state wave function can be used to probe the effective
dimension of asymmetric cold atomic traps for Feshbach resonances tuned close
to the Efimov limit.
