AXIONIC EXTENSION OF THE EINSTEIN-DIRAC-AETHER THEORY: DEGENERACY REMOVAL WITH RESPECT TO SHEAR OF THE AETHER FLOW

Efremova A.O., Balakin A.B.

We consider dynamics of the quartet of interacting cosmic substrata, which includes the dynamic aether, presented by the unit timelike vector field, the axionic dark matter, described by the pseudoscalar field, the spinor field associated with fermion particles, and the gravity field. The extended set of master equations is derived based on the idea that the potential of the axion field to be the function of seven arguments. The first one is, standardly, the pseudoscalar field; the second and third arguments are the fundamental spinor invariant and pseudoinvariant; the fourth and fifth ones are the aether-axion cross-invariants and cross-pseudoinvariants; the sixth argument is the expansion scalar, and the seventh one is the square of tensor of the shear of the aether flow. The complete set of Master equations is derived and prepared for analysis.

Keywords: Dirac spinor field, axion, aether.
