FROM SKYRMIONS TO THE NUCLEON-NUCLEON POTENTIAL

Abstract

Recent work on the derivation of the nucleon-nucleon potential from interacting solitons in the Skyrme model is reviewed. A general introduction to the Skyrme and extended Lagrangians is given and the quantization of the solitons of these theories is described. Results from various studies of the two-skyrmion interaction using ansätze, time-dependent numerical simulations and time-independent constrained calculations are discussed. Improvements which include intermediate deltas in these latter calculations are presented and the resulting nucleon-nucleon interaction compares well with phenomenological potentials.
