Creating synthetic hadrons

[bede]

My son asked me a question I could not answer the other day (sorry I'm a biophysicist). Physicists have created synthetic elements by combining sufficient protons and neutron into a nucleus. Has anyone ever created a synthetic hadron by combining quarks? Is that even at all possible?

My guess was no since it would require an inordinate amount of energy.

Since quarks can't be set free from the hadrons, they can't be used to make combinations. Hadrons of various sorts are created by banging other hadrons together at high speed.
