  bibo_abstract:
  - We study few-body bound states of charged particles subject to attractive zero-range/short-range
    plus repulsive Coulomb interparticle forces. The characteristic length scales
    of the system at zero energy are set by the Coulomb length scale D and the Coulomb-modified
    effective range r eff. We study shallow bound states of charged particles with
    D >> r eff and show that these systems obey universal scaling laws different from
    neutral particles. An accurate description of these states requires both the Coulomb-modified
    scattering length and the effective range unless the Coulomb interaction is very
    weak (D -> ). Our findings are relevant for bound states whose spatial extent
    is significantly larger than the range of the attractive potential. These states
    enjoy universality – their character is independent of the shape of the short-range
    potential.@eng
