Query: Fractal structure of near-threshold quarkonium production off cold
  nuclear matter   We investigate near-threshold production of quarkonium resonances in cold
nuclear matter through a scaling theory with two exponents which are fixed by
existing data on near-threshold J/psi production in proton-nucleus collisions.
Interestingly, it seems possible to extend one of the multifractal dimensions
to the production of other mesons in cold nuclear matter. The scaling theory
can be tested and refined in experiments at the upcoming high-intensity FAIR
accelerator complex in GSI.
