| Popis: | The Abelian gauge symmetry proposed by Hermann Weyl is generalized to its non-Abelian extension. Afterwards the standard model is generalized to incorporate the Abelian and non-Abelian Weyl symmetry. This symmetry extension brings new gauge particles that can be potential candidates for the dark matter. It also naturally introduces a second scalar field into the theory. The breaking of the Weyl symmetry turns this scalar field into a dimensional constant, making the Higgs as the only scalar component in the standard model. In addition to the expected benefits, there are three unexpected bonuses: (1) it brings some new understanding of the parity violation; (2) it provides an answer to the sign problem in the Higgs mechanism; (3) it gives some new perspectives on the nature of the neutrino: non-Abelian Weyl symmetry demands that there \textit{must be} right-handed netrino; furthermore, the smallness of the neutrino mass is protected by the non-Abelian Weyl symmetry.
