Abstract

We explore the freedom of choosing subtraction points in the renormalizable σ model of π→ and σ. Phase shifts are computed from Padé approximants in the one-loop approximation. Comparisons are made with a previous calculation and an SU3 σ-model calculation. The phase of the scalar form factor of the pion is presented. © 1974 The American Physical Society.
