SU(2) x U(1) Gauge Gravity
International Journal of Theoretical Physics 34(9), 1981-2001 (1995).

Abstract: We propose a Lorentz-covariant Yang-Mills "spin-gauge" theory, where the function valued Pauli matrices play the role of a non-scalar Higgs-field. As symmetry group we choose SU(2) x U(1) of the 2-spinors describing particle/antiparticle states. After symmetry breaking a non-scalar Lorentz-covariant Higgs-field gravity appears, which can be interpreted within a classical limit as Einstein's metrical theory of gravity, where we restrict ourselves in a first step to its linearized version.
