Elimination of the Landau Ghost from Chiral Solitons

High Energy Physics - Phenomenology 2009-09-25 v1

Abstract

We show a practical way based on the K\"{a}ll\'{e}n-Lehmann representation for the two-point functions to eliminate the instability of the vacuum against formation of small sized meson configurations in the chiral σ\sigma model.
