A covariant view on the nucleons’ quark core

Abstract: Established results for the quark propagator in Landau gauge QCD, together with a detailed comparison to lattice data, are used to formulate a Poincaré-covariant Faddeev approach to the nucleon. The resultant three-quark amplitudes describe the quark core of the nucleon. The nucleon's mass and its electromagnetic form factors are calculated as functions of the current quark mass. The corresponding results together with charge radii and magnetic moments are discussed in connection with the contributions from va… Show more

“…The covariant amplitudes are then used for the subsequent calculation of form factors or other transiton amplitudes [66][67][68][69][70][71][72][73][74][75][76][77]. For our discussion herein, we only sketch the essential aspects related to the homogenous quark-bilinear BSE.…”

“…The RL truncated DSEs have been widely used with the aim to reproduce hadron observables: masses and electromagnetic properties of mesons and baryons, e.g. [5,6,7,8,9,10]. However, evidence has been provided that important corrections to RL truncation are mesonic effects in the quark and quark-gluon-vertex DSEs, see e.g.…”
