Faddeev equation for heavy baryons in the quark–diquark picture
نویسندگان
چکیده
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 the results for the heavy baryon spectrum using a static approximation.

Heavy baryons in the quark–diquark picture
We describe heavy baryons as bound states of a quark and a diquark. For this purpose we derive the Faddeev equation for baryons containing a single heavy quark from a Nambu– Jona-Lasinio type of model which is appropriately extended to include also heavy quarks. The latter are treated in the heavy mass limit. The heavy baryon Faddeev equation is then solved using a static approximation for the ...
متن کاملOctet and Decuplet Baryons in a Confining and Covariant Diquark-quark Model *
We treat baryons as bound states of scalar or axialvector diquarks and a constituent quark which interact through quark exchange. We obtain fully four-dimensional wave functions for both octet and decuplet baryons as solutions of the corresponding Bethe-Salpeter equation. Applications currently under investigation are: electromagnetic and strong form factors and strangeness production processes...
متن کاملWeak Semileptonic Decays of Heavy Baryons Containing Two Heavy Quarks
In the heavy quark limit a heavy baryon which contains two heavy quarks is believed to be composed of a heavy diquark and a light quark. Based on this picture, we evaluate the weak semileptonic decay rates of such baryons. The transition form factors between two heavy baryons are associated with those between two heavy mesons by applying the super avor symmetry. The e ective vertices of the W-b...
متن کاملCurrent, Pion and Photon Transitions between Heavy Baryons
I discuss the structure of current-induced bottom baryon to charm baryon transitions, and the structure of pion and photon transitions between heavy charm or bottom baryons in the Heavy Quark Symmetry limit as mQ → ∞. The emphasis is on the structural similarity of the Heavy Quark Symmetry predictions for the three types of transitions. The discussion involves the ground state s-wave heavy bary...
متن کاملBaryons in and beyond the quark-diquark model
We examine the nucleon’s electromagnetic form factors in a Poincaré-covariant Faddeev framework. The threequark core contributions to the form factors are obtained by employing a quark-diquark approximation. We implement the selfconsistent solution for the quark-photon vertex from its inhomogeneous Bethe-Salpeter equation. We find that the resulting transverse parts which add to the Ball-Chiu v...
