Mass shift of sigma-Meson in Nuclear Matter
J. R. Morones-Ibarra, Monica Menchaca Maciel, Ayax Santos-Guevara +1
The propagation of sigma meson in nuclear matter is studied in the Walecka model, assuming that the sigma couples to a pair of nucleon-antinucleon states and to particle-hole state…
Statistical analysis of the sigma meson considered as two-pion resonance
M. C. Menchaca Maciel, J. R. Morones Ibarra
It was found that the most simple analysis in the linear σ- model, where the sigma meson couples in vacuum to two virtual pions, predicted the most typical values for the σ-mass an…
Sigma meson resonance and its coupling constant
M. C. Menchaca Maciel, J. R. Morones Ibarra
We study two coupling constants reported as predictions of the sigma model. We obtain an spectral distribution, in terms of the σmeson regularized self- energy in one loop order, w…
