概要

• 論文の詳細を見る

• We study a quantum stability of O(4) nonlinear σ-model with the Wess-Zumino term. Deriving a Ward-Takahashi identity, we show the renormalizability of this model and prove that a particular value of the coupling constant λ^2=2π/k stays unchanged even after quantum corrections are included. As a complementary check we have calculated a one-loop divergent part of the effective action.
