Pion Form Factor and Ambiguities in a Renormalizable Version of the Nambu-Jona-Lasinio Model

B. M. Rodrigues, A. L. Mota

We analyze the presence of an ambiguity in the pion electromagnetic form factor within a renormalizable version of the Nambu-Jona-Lasinio model. We found out that the ambiguity pre…
