• and the related problem of fermion families. Recently I have put forward a new idea, in which fermion and vector boson states are constructed from constituents ('tetrons'), which take the geometrical form of a tetrahedron or a cube. The model encodes all observed structures and phenomena of elementary particle physics in group theoretic items of the tetrahedral group which is isomorphic to the permutation group S4. Details of the model like symmetry breaking, distribution of charges and mass generation are worked out. pdf-files to download (ordered according to time):

  Space and Family, my first paper on the subject, contains the main idea and a geometrical interpretation, which is still relevant at this time e.g. for inclusion of gravity. Spacetime is considered discrete at very small distances, with only permutation symmetry transformations remaining relevant. When a fermion tetrahedron moves through a gravitational field, the directions of its 4 tetrons are given by the 4-bein which defines the gravitational field at that point.

  World of Tetrons contains a first approach to the formation of vector bosons from tetrons
