Analytic expressions for these quantities are obtained in terms of the parameters of low energy physics (pion decay constant and the pion mass). Good results have been obtained in comparison with my previous works and with the other models. 关键词: Nucleon Sigma-term Linear sigma model DOI: ...
The K0, K0 → 2π amplitudes are represented with emphasis on the recently established value of ϵ′[1]. Linear σ-models as partially integrated effective functionals are analysed in their features which contrast with the nonlinear variant, with respect to the long range aspect of the ΔI ...
We calculate the physical mass and the width of the sigma meson by considering that it couples in vacuum to two virtual pions. The mass is calculated by using the spectral function, and we find that it is about 600 MeV. In addition, we obtained 220 MeV as the value for the width of ...
where \(\rho \) is an auxiliary fixed constant, the divergent part will have the same value. The same property was recently noticed in the four-dimensional Yang–Mills theory [48]. Actually, this feature follows from the fact that the two-loop divergent part is proportional to the logarithm...

We study the pion, sigma and nucleon propagators of the linear σ-model in the one-loop approximation. We show that in the renormalized model the meson propagators exhibit imaginary poles. Such nonphysical poles disappear when a cutoff is introduced. The maximum of this cutoff value is shown...
