Large-Nc Consistency of Chiral Nuclear Forces

Published in Ruhr-Universität Bochum (Master thesis)

Keywords: Nuclear Physics, Nuclear Forces, Chiral Perturbation Theory, Large-Nc QCD


The work tests the consistency of nucleon-nucleon forces derived by two different approximation schemes of Quantum Chromodynamics (QCD)—the chiral perturbation theory ($\chi$PT) and large-Nc QCD. The approximation schemes and the derivation of the potential are demonstrated in this work. The consistency of the chiral potential, derived using the method of unitary transformation, is verified for chiral orders $Q^\nu$ for $\nu = 0,2,4$. Used methods, as well as possible extensions for higher orders, are presented.
