Abstract	There is a wide litterature about deformed interaction vertices with Planck-scale-deformed spacetime symmetries. Since the deformation scale is far from experimental testing, this vertices have been studied mainly at the leading order. In this talk we will show a study at all orders of some examples of such vertices, taking into account the case in wich all the interacting particle "feel" the same spacetime symmetries deformation, and a new class of vertices in wich indeed different particles "feel" different spacetime symmetries deformations. We will point out the qualitative differences between the ordinary Poincaré spacetime symmetries case and the two different type of deformations.
