Extended pure Yang-Mills gauge theories with scalar and tensor gauge fields

The usual abelian gauge theory is extended to an interacting Yang-Mills-like theory containing vector, scalar and tensor gauge fields. These gauge fields are seen as components along the Clifford algebra basis of a gauge vector-spinorial field. Scalar fields φ naturally coupled to vector and tensor fields have been found, leading to a natural φ4 coupling in the lagrangian. The full expression of the lagrangian for the euclidean version of the theory is given.
