Elastic nucleon-nucleon scattering in a gauge field theory

Abstract

Nucleon-nucleon scattering is studied in a spontaneously broken gauge field theory with the gauge boson describing the $\rho$ meson. Gauge invariance is demonstrated explicitly. An inversion of the ${}_{}{}^3{}_{}{}^{}P_0^{}{}_{}{}^{}$ phase shift (but no zero) is obtained in a [$\frac{1}{1}$] scalar Padé approximation.
