Quark structure and nuclear effective forces.
We formulate the quark meson coupling model as a many-body effective Hamiltonian. This leads naturally to the appearance of many-body forces. We investigate the zero range limit of the model and compare its Hartree-Fock Hamiltonian to that corresponding to the Skyrme effective force. By fixing the three parameters of the model to reproduce the binding and symmetry energy of nuclear matter, we f...
متن کاملNuclear Forces and Nuclear Structure
After a historical review, I present the progress in the field of realistic NN potentials that we have seen in recent years. A new generation of very quantitative (high-quality/high-precision) NN potentials has emerged. These potentials will serve as reliable input for microscopic nuclear structure calculations and will allow for a systematic investigation of off-shell effects. The issue of thr...
متن کاملMore effective theory of nuclear forces
I outline why the renormalisation group is needed to analyse the scale dependence and hence determine the power counting for effective theories of strongly interacting systems. I summarise the results of several such analyses for two-and three-body forces in nuclear physics. These show that a number of terms should be significantly promoted relative to naive dimensional analysis.

In this lecture series, I present the recent progress in our understanding of nuclear forces in terms of chiral effective field theory.
متن کاملRealistic Effective Interactions and Nuclear Structure Calculations
We address the two main questions relevant to microscopic nuclear structure calculations starting from a free NN potential. These concern the accuracy of these kinds of calculations and the extent to which they depend on the potential used as input. Regarding the first question, we present some results obtained for nuclei around doubly magic Sn and Pb by making use of an effective interaction d...
