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…

A Calculation of the Sigma Meson Mass in Nuclear Matter
J. R. Morones-Ibarra, Ayax Santos-Guevara
We calculate the mass and width of the sigma meson in nuclear medium by considering that it couples to two virtual pions and to a pair of nucleon-antinucleon states and to particle…
