What is the Real Structure of Fundamental Forces?

Based on general considerations, the Standard Model of particle physics with its extensions (SM) can be ruled out as a valid theory of fundamental forces: it requires far too many parameters, which are not determined from first principles. The only way to uncover the real structure of elementary forces is to resort to a complete and fundamental theory without external parameters. This requirement is fulfilled in a finite theory, based on an extension of the QED Lagrangian by boson-boson coupling, with massless elementary fields, charged and neutral elementary fermions (quantons) and gauge bosons. In this description the observed bound states of nature, hadrons, leptons, atoms and gravitational objects are understood as stationary systems of quantons bound by electric or magnetic forces. Other fields do not exist.
