Weyl spinors with proto-charges as the bases for elementary particles

We present a conceptual overview of a new model of elementary particles with a substructure that the Gell-Mann-Nishijima formula seems to suggest. This set of Weyl spinors with proto-charges produces all the known elementary fermions from their conjugate pairs, and the elementary bosons as their composites. The model naturally suggests three generations of fermions, and yields SU(3) SU(2) U(1) symmetry as its low energy approximation. The model contains a new type of massive neutral bosons as a dark matter candidate and proposes a new way to explain neutrino oscillation while keeping its left-handedness. In this model, the strong and the electromagnetic interactions are integrated at the fundamental level, while the weak interaction works as the flavor changing mechanism that stems from the two-component structure of the spinors. We also explore the implications of our model for the Einstein-Cartan theory in which spinors play an important role in our understanding of gravity.
