Nucleon mass from a covariant three-quark Faddeev equation.
We report the first study of the nucleon where the full Poincaré-covariant structure of the three-quark amplitude is implemented in the Faddeev equation. We employ an interaction kernel which is consistent with contemporary studies of meson properties and aspects of chiral symmetry and its dynamical breaking, thus yielding a comprehensive approach to hadron physics. The resulting current-mass e...
متن کاملFaddeev equation for heavy baryons in the quark–diquark picture
We derive the Faddeev equation for baryons containing a single heavy quark as an effective two–body equation containing quarks and diquarks. The quark interaction is assumed to originate from a Nambu-Jona-Lasinio type interaction, extended to include also heavy quarks which are treated in the heavy mass limit. From this we first estimate the light and heavy diquark properties and then present t...
متن کاملGoldberger–Treiman Relation and gπNN from the Three Quark BS/Faddeev Approach in the NJL Model
A systematic evaluation method of matrix elements of quantum one-body operators between nucleon states in the three-quark Bethe-Salpeter(3qBS)/Faddeev approach in the NJL model is reviewed. We do not confine ourselves to a particular truncation scheme of the 3qBS kernel. One of our main aims is to derive a general condition to be imposed on a given BS kernel in order that the PCAC relation is s...
متن کاملOn the treatment of confinement in three-quark calculations
The treatment of confining interactions in non-relativistic three-quark systems is revised. Usually in the Faddeev equations the Faddeev components are coupled by the total potential. In the new treatment the Faddeev components are coupled only by the non-confining short-range part of the potential, allowing thus its channel-by-channel investigation. The convergence in angular momentum channels...
