A possibility of describing a sequential gauge symmetry as a part of a tetrahedron rotational symmetry and its implications

Abstract

We present a method in which the dimension-five and -six terms in a sequential gauge can coexist with that in a non-sequential gauge under a tetrahedron rotational symmetry. We start with the contents in the model proposed in a sequential gauge, meeting the conditions for the contents to be described in the rotational symmetry. Given that the breaking of the symmetry takes place in the dimension-five and -six terms via the flavor-specific Higgs scalars, we address how introducing the non-sequential contents can be realized. In doing so, we illustrate that the terms in the sequential gauge could be understood as the higher-order terms, the correction terms, and that in the non-sequential gauge as the leading order term. Our result could be understood as an illustration of introducing the sequential gauge as a reason for the mixing as having non-zero left-handed rotational matrix in the quark and the lepton sectors, how the mixing in the charged lepton sector can be small compared to that of the neutral sector, and how the sequential and the non-sequential gauge terms can coexist without introducing super-symmetry.
