Coarse graining Nuclear Interactions
We consider a coarse graining of NN interactions in coordinate space very
much in the spirit of the well known Vlowk approach. To this end we sample the
interaction at about the minimal de Broglie wavelength probed by NN scattering
below pion production threshold. This amounts to provide a simple delta-shell
potential plus the standard OPE potential above 2 fm. The possible
simplifications in the Nuclear many body problem are discussed.Comment: Presented by RNP at the Erice School on Nuclear Physics 2011: From
