A condensed introduction to quantum gauge theories is given in the perturbative S-matrix framework; path integral methods are used nowhere. This approach emphasizes the fact that it is not necessary to start from classical gauge theories which are then subject to quantization, but it is also possible to recover the classical group structure and coupling properties from purely quantum mechanical...

Abstract In this paper I propose solutions to the nature of Dark matter, Dark energy, Matter and the Matter-Antimatter asymmetry. The real spin representations of a 7d complex space are assumed to be the source of a chiral gauge group SU(8)xU(1) and a spin 2 quaternion field. The integral of the probability density of the spin 2 field results in a lower bound for r and consequently the Schwarzs...
