The emergence of an infinite number of bound states in a system of three bosons, given the s-wave two-body binding energy is at the dissipation threshold, was first predicted by V. Efimov in 1970, and finally verified experimentally during the last decade. Since then, studies are exploring this effect in one- and two-dimensional systems, for different types of two-body interactions (long- and short-range) as well as symmetries of the underlying two-body resonance.

In this poster we present a system containing one light particle and two identical heavy ones, provided i) all particles move on a line, and ii) the heavy-light interaction potential has a p-wave (asymmetric) resonance. Within the Born-Oppenheimer approach we find the corresponding energy spectrum and the number of three-body bound states.
