Four families in preon model

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

We account for the number of families of quarks and leptons by considering a composite model of preon. The doublets are composed of preons and antipreons. From theC, P, T transformation and theSU(2)L×U(1) gauge theory, it is shown that there are just four families and, moreover,CP is violated in each family.
