The theory in which these particles appear is an SU(3) gauge theory, and particles composed only of them are predicted to exist, but the only candidate known, f(1710), decays too quickly into K-mesons. During the first ten microseconds after the Big Bang, the state of matter where hadrons are decomposed that was said to have formed is known as a plasma of quarks and these particles. A vector gauge boson of spin 1, they have only two polarization states and have eight independent types, and although their exchange results in a change of color, the quarks maintains the balance of color. Carriers of the strong nuclear force, these are, FTP, which subatomic particles that cause quarks to interact and thus the binding of protons and neutrons in nuclei
