Title: Relativistic particle quantum dynamics and three-body forces in the three-nucleon system

Abstract

It is found that questions concerning the effects of relativistic invariance can and should be separated from questions concerning the relevant subnucleon degrees of freedom that should be treated explicitly. It is possible to formulate Poincare invariant quark models with a finite number of quarks. In such models hadron states have definite spin, a feature which is absent in light-front perturbative treatments of QCD. Substantial differences from nonrelativistic quark models can occur for very light quarks. It is possible to formulate a Poincare invariant three-nucleon dynamics which has the same qualitative features as the nonrelativistic dynamics, including semiphenomenological two- and three-body forces. The invariance requirements do not constrain the allowable two-body forces and impose only a weak constraint on acceptable three-body forces.
