Nuclear Scales
Abstract
Nuclear scales are discussed from the nuclear physics viewpoint. The conventional nuclear potential is characterized as a black box that interpolates nucleonnucleon (NN) data, while being constrained by the best possible theoretical input. The latter consists of the longerrange parts of the NN force (e.g., OPEP, TPEP, the $\pi$$\gamma$ force), which can be calculated using chiral perturbation theory and gauged using modern phaseshift analyses. The shorterrange parts of the force are effectively parameterized by moments of the interaction that are independent of the details of the force model, in analogy to chiral perturbation theory. Results of GFMC calculations in light nuclei are interpreted in terms of fundamental scales, which are in good agreement with expectations from chiral effective field theories. Problems with spinorbittype observables are noted.
