Compositeness and spatial extension of fundamental particles justified by introducing a dual space concept — •Hans-Dieter Herrmann — Berlin

The assumption that organisms consist of cells and molecules consist of atoms is not analogously applicable to fundamental particles. Compositeness of leptons and quarks in space-time is excluded by experiment. We propose a dual space concept in particle physics, which complements space-time by an extra space, fixed to an individual particle as an 'eigenspace'. The eigenspace of a particle resembles the space spanned by body-fixed coordinates of a satellite, a drone or a spinning top. The body-fixed coordinates complement the lab-fixed or earth-fixed coordinates of a moving object, which define the common space-time. The twofold existence of natural systems in two spaces is investigated at different levels of reality. At the level of subatomic particles we identify space-time as the `common space', however the `eigenspace' of fundamental particles is missing. An inaccessible cylindrical `eigenspace' is proposed where fundamental particles appear composited and spatially extended. Intrinsic properties of a particle such as invariant energy, spin, and magnetic moment have its origin in the eigenspace. The consequences of the dual space concept for the cosmic inflation and the nature of dark matter are discussed. A conjecture on the emergence of space-time caused by the emergence of fundamental particles from sub-particles is developed.
