摘要: Whether the σ-meson (f0(600)) exists as a real particle is long-standing problem in both physics and nuclear physics. In this work, we analyse deuteron binding energy linear σ-model by fitting data, are able to determine range of mσ also investigate applicability for interaction between hadrons region MeVs. Our result shows that best fit data others advocates narrow mass 520 ≤ 580 MeV concrete values depend on input parameters such couplings. Inversely experimental one can set constraints couplings other relevant phenomenological model.
