“…At l o w energy this`background' amplitude arises naturally when subtracting the -function which is present in the central part of the Yukawa potential. The subtraction of this unphysical term allows to obtain excellent agreement with the data, as can be seen in g. 1b, where the data are compared with the potential model calculation of the Paris group [7]. Several mechanisms, like the noexchange model [8], have been proposed to motivate the subtraction of the -function.…”

A recent experiment at LEAR, the CERN Low Energy Antiproton Ring, has provided very precise dierential cross-section data for the pp ! nn chargeexchange reaction. When performing the extrapolation procedure to the pion pole originally proposed by G. F. Chew the data exhibit the same dynamical mechanism than the np ! pn line reversal reaction. The residue at the pole is consistent with the known value of the charged NN coupling constant, as expected from charge conjugation invariance.

“…Our main focus concerns an alternative approach which starts with the dispersion relation analysis of NN scattering by the Paris [46] and Stony Brook [49] groups in the mid-70s. That work demonstrated in a clear, model independent way that the dominant, intermediate range, attractive NN force was an iso-scalar Lorentz-scalar.…”

The strong force that binds atomic nuclei is governed by the rules of Quantum Chromodynamics. Here we consider the suggestion the internal quark structure of a nucleon will adjust self-consistently to the local mean scalar field in a nuclear medium and that this may play a profound role in nuclear structure. We show that one can derive an energy density functional based on this idea, which successfully describes the properties of atomic nuclei across the periodic table in terms of a small number of physically motivated parameters. Because this approach amounts to a new paradigm for nuclear theory, it is vital to find ways to test it experimentally and we review a number of the most promising possibilities.

“…The starting point of the model is the Paris NN potential model (Lacombe 1975(Lacombe , 1980(Lacombe and 1981 The potential has the form V(NN)=U(NN)-i W(NN). Here U(NN) is the G-parity transformed medium and long range parts of the Paris NN potential complemented by a quadratic cut -off function below 0.9 fm.…”
