Calculation of fo and m_σ in a QCD-Based Model Field Theory
Calculation of fo and m_σ in a QCD-Based Model Field Theory
摘要
With the recently obtained vacuum configuration of the bilocal field,we discuss the decay con-stant f_σ and m_σ of σ-meson in a quantum Chromodynamics(QCD)-based model field theory.Reasonablevalues of f_σ and m_σ are obtained.
