Mixing of scalar meson and baryon-baryon interaction

At quark level,we study the effect of ideal mixing of singlet σ 0 and octet σ 8 scalar mesons on baryon-baryon interaction in the chiral SU（3） quark model.We solve the resonating group method equation for scattering process and bound state.The results show that the binding energy of deuteron and nuc...

Description
Summary:At quark level,we study the effect of ideal mixing of singlet σ 0 and octet σ 8 scalar mesons on baryon-baryon interaction in the chiral SU（3） quark model.We solve the resonating group method equation for scattering process and bound state.The results show that the binding energy of deuteron and nucleonnucleon and hyperon-nucleon scattering data can be reasonably described for ideal mixing.Taking the same parameters we used in the scattering calculation,we further investigate the possible dibaryons and find the binding energy of （ΩΩ） ST =00 and （Ξ ＊Ω） ST =0 1 2 can be reduced a lot for ideal mixing.
