Explain how quarks create particles and antiparticles

Three quarks and a gluon make either a proton or neutron. The gluon pulls the three quarks back within force boundaries. The pull of the gluon increases with distance. If for an instance, you succeed in freeing a quark with a great burst of energy, some of the energy will transform itself into other quarks and ant quarks. One of the new quarks will embrace the quark and form a pion. (This explains the particle side of the equation)

What creates the antiparticle side of the equation? Is it the anti quark?

You don't need string theory to get antiparticles. Dirac predicted the existence of antiparticles in coming up with a relativistically invariant wave equation (akin to Schroedinger's equation).

The baryons and mesons that are composites of quarks have antiparticle twins made up of the anti-versions of the same quarks. Baryons are composed of 3 ordinary quarks, so their antiparticles are made up of the 3 corresponding antiquarks. Mesons are made up of one quark and one antiquark, although some are superpositions of two quark-antiquark pair states. The antimesons have the corresponding antiquark-quark pair. For example, the pi+ meson consists of an up quark and an anti-down quark. It's antiparticle (called pi-) is an anti-up and a down. The pi0 meson is a superposition of up-antiup and down-antidown, and is thus its own anti-particle.

Thanks for the answer. The superposition explanation was helpful.

You said "what" creates the antiparticle, not "how". I'm leaning towards the way the question is being asked that makes it harder for me to isolate an answer.

Some theories are proven with other theories so without a depiction showing common (to us) theories to pull from it's hard to provide an answer that works the first time.

I did find a wonderful niche of information on the topic though. Thought I'd share.

Ok, lets go with your suggestion. How are antiparticles created? String theory suggests that particles and antiparticles exist. Explain antiparticles.

I missed your comment even though I've selected to be notified when comments are made. I would have participated further otherwise. :)
