Nuclear Symmetry Energy from microscopic manybody theory M
Nuclear Symmetry Energy from microscopic many-body theory M. Baldo INFN, Catania
Comparison with phenomenology at saturation Not all the considered microscopic EOS around saturation are compatible with the phenomenological boundaries on the parameter L 40. 5 < L < 61. 9 Me. V ( Lattimer & Lim ) We will focus on the overall trend of the symmetry energy as a function of density
Possible effect of TBF on Symmetry energy
However…. .
Density dependence up to saturation
The predictions of the different EOS look restricted to a relatively narrow band Phenomenology may be compatible with such restricted area or possibly provides further restrictions

Relevance of three-body correlations for the QM interaction This is at variance with respect to the other NN interaction
