Models for nuclear forces and derivation of non-relativistic expressions

When we perform similar non-relativistic expansions for scalar and vector mesons we obtain for the σ meson Vσ=g2σNN1k2+m2σ(1+q22M2Nk28M2NLS2M2N). We note an attractive central force and spin-orbit force. This term has an intermediate range. We have defined 1/2(p1+p1)=q. For the full potential add the exchange part and the isospin dependence as well.
