# Unification mechanism for gauge and spacetime symmetries

@article{Lszl2015UnificationMF, title={Unification mechanism for gauge and spacetime symmetries}, author={Andr{\'a}s L{\'a}szl{\'o}}, journal={Journal of Physics A: Mathematical and Theoretical}, year={2015}, volume={50} }

A group theoretical mechanism for unification of local gauge and spacetime symmetries is introduced. No-go theorems prohibiting such unification are circumvented by slightly relaxing the usual requirement on the gauge group: only the so called Levi factor of the gauge group needs to be compact semisimple, not the entire gauge group. This allows a non-conventional supersymmetry-like extension of the gauge group, glueing together the gauge and spacetime symmetries, but not needing any new exotic…
