# Consistency of Nuclear Forces in the Limit of Large-Nc

### By Christopher Körber

#### Conference Talk at Students Exchange Week in Bad Honnef – April, 2015

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

Conference talk on 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. 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.
