Approach unifying spins and charges

Abstract:

In the Approach unifying spin and charges spinors in (13+1)-dimensional space carry only the spin and interact through vielbeins and two kinds of spin connections. The starting symmetry of the Lagrangian breaks at low energies to manifest all the Standard model degrees of freedom including families and Yukawa couplings. Assumptions about the break of symmetries lead to predictions about the 4th family and possible dark matter candidates.
