Towards a dynamical preon model

We discuss further the recently proposed ''primordial'' quantum chromodynamics, where a massive Fermi-Bose couple of two colour triplets delta and chi of spin 1/2 and 0, respectively, and of equal charge - 1/3 interacts with a colour octet of massless vector gluons. The ''preons'' delta and chi form bound states #betta#sub(e) = delta chi-bar, e=delta(chichi)sub(P) (colour singlets) and u=delta-bar chi-bar, d=delta-bar (chichi)sub(P) (colour triplets). Other preon bound states also exist and are briefly reviewed. (author)
