# Can pair production produce any particle/anti-particle pair?

Hopefully this one'll be a fairly easy answer. My understanding of pair production is that it is a simple transfer of momentum/energy in which an incident particle looses energy after a scattering interaction with a nucleus (or other more massive (?) particle) and that this energy is converted to a particle/antiparticle pair. Pretty much all of the sources that I've consulted (Introduction to Elementary Particles by Griffith, Mando & Ronchi 1952, etc.) talk about pair production of electrons, muons, and perhaps pions, (~ 0.5, 105, and 137 MeV/$c^2$ in mass respectively); but I've only found a very limited number of sources that mention higher energy pair production.

My basic question is whether it's theoretically possible for any particle/anti-particle pair (e.g. $D\overline{D}$ meson pair production) to be produced by a collision of sufficient energy within the constraint that all conserved quantum numbers must sum to 0? Or is there some upper limit imposed by theory? Obviously there is a practical upper limit, based upon the maximum energy of incident particle radiation observed in nature, or generated in a particle accelerator, but is there a theoretical upper limit to the particle mass of pair production?
