A new criterion to extend the Standard Model of particle physics is proposed: the symmetries of physical microscopic forces originate from the automorphism groups of main Cayley–Dickson algebras, from complex numbers to octonions and sedenions. This correspondence leads to a natural enlargement of the color sector, from a SU(3) gauge group to an exceptional Higgs-broken G(2) group. In this picture, an additional ensemble of massive G(2)-gluons emerges, which is separated from the particle dynamics of the Standard Model and might play the role of dark matter.
