  It is assumed that the two-component spinor formalisms for curved spacetimes
that are endowed with torsionful affine connexions can supply a local
description of dark energy in terms of classical massive spin-one uncharged
fields. The relevant wave functions are related to torsional affine potentials
which bear invariance under the action of the generalized Weyl gauge group.
Such potentials are thus taken to carry an observable character and emerge from
contracted spin affinities whose patterns are chosen in a suitable way. New
covariant calculational techniques are then developed towards deriving
explicitly the wave equations that supposedly control the propagation in
spacetime of the dark energy background. What immediately comes out of this
derivation is a presumably natural display of interactions between the fields
and both spin torsion and curvatures. The physical properties that may arise
directly from the solutions to the wave equations are not brought out.
