Abstract
 
We define a new algebraic extension of the  Poincaré symmetry;
 this algebra  is used to implement a field theoretical model.
 Free Lagrangians are explicitly constructed; several discussions
 regarding degrees of freedom, compatibility with Abelian gauge invariance etc.
 are done. Finally we analyse the possibilities of interaction terms for this model.
  
Key words:
extensions of the Poincaré algebra; field theory; algebraic methods; Lie (super)algebras; gauge symmetry.
