Retardation effects from quark confinement on low-energy nucleon dynamics

Abstract

W'e investigate effects from quark confinement on low-energy nucleon dynamics. These effects are shown to give rise to a peculiar dynamical situation: Low-energy nucleon dynamics is not Hamiltonian and is governed by a nonlocal-in-time interaction operator. In the leading order of the two-nucleon EFT we show that after renormalization the nucleon dynamics is governed by the same interaction operator. : 13.75.Cs, 24.85.+p PACS
