Equivalence of light-front and covariant approaches in meson-baryon interactions
We demonstrate the equivalence of the light-front, equal-time and covariant formulations in meson-baryon interactions. In particular, we discuss the self-energy Sigma of a nucleon dressed by pion loops with the pseudovector piNN coupling. It is shown that the leading nonanalytic behavior of Sigma is equivalent whichever formulations are used for the derivation.
