Higher derivative terms in the πΔN interaction: some phenomenological consequences
Alejandro Mariano, Daniel Badagnani, Cesar Barbero
In this paper we implement for the first time the use of a πNΔ(1232) vertex interaction containing both first and second order derivative terms, as required by renormalization cons…

Inconsistency of the interactions between pseudoscalar, spinor and Rarita-Schwinger fields
D. Badagnani, A. Mariano, C. Barbero
We perform the Dirac quantization of RS fields interacting with a spinor and the first derivative of a pseudoscalar field. We achieve the calculations for two forms of this interac…

About consistence between pi N Delta spin-3/2 gauge couplings and electromagnetic gauge invariance
D. Badagnani, C. Barbero, A. Mariano
We analyze the consistence between the recently proposed "spin 3/2 gauge" interaction for the Delta resonance with nucleons and pions, and the fundamental electromagnetic gauge inv…
