Query: Electro-weak Model within the framework of Lorentz gauge theory:
  Ashtekar variables?   The Electroweak (EW) model is geometrized in the framework of a 5D gauge
theory of the Lorentz group, after the implementation of the Kaluza-Klein (KK)
paradigm. The possibility of introducing Ashtekar variables on a 5D KK manifold
is considered on the ground of its geometrical structure.
