Query: On the generalized spinor classification: Beyond the Lounesto's
  Classification   In this paper we advance into a generalized spinor classification, based on
the so-called Lounesto's classification. The program developed here is based on
an existing freedom on the spinorial dual structures definition, which, in a
certain simple physical and mathematical limit, allows us to recover the usual
Lounesto's classification. The protocol to be accomplished here gives full
consideration in the understanding of the underlying mathematical structure, in
order to satisfy the quadratic algebraic relations known as Fierz-Pauli-Kofink
identities, and also to provide physical observables. As we will see, such
identities impose a given restriction on the number of possible spinorial
classes allowed in the classification. We also expose a mathematical device
known as \emph{Clifford's algebra deformation}, which ensures real spinorial
densities and holds the Fierz-Pauli-Kofink quadratic relations.
