Nucleon Form Factors in the Covariant Diquark-Quark Model
R. Alkofer, M. Oettel
The nucleon is described as a bound state of a quark and an extended diquark. Hereby the notion ``diquark'' refers to the modelling of separable correlations in the two-quark Green…
Octet and Decuplet Baryons in a Covariant and Confining Diquark-Quark Model
M. Oettel, G. Hellstern, R. Alkofer +1
The baryon octet and decuplet masses and Bethe-Salpeter vertex and wave functions are calculated in the ladder approximation to the quark exchange between a scalar or axialvector d…
Diquark confinement in an extended NJL model
G. Hellstern, R. Alkofer, H. Reinhardt
In a Nambu-Jona-Lasinio model supplemented with an infrared cutoff in addition to the ultraviolet cutoff we study the issue whether diquarks are confined when the model is extended…
Nucleon Form Factors in a Covariant Diquark-Quark Model
G. Hellstern. R. Alkofer, M. Oettel, H. Reinhardt
In a model where constituent quarks and diquarks interact through quark exchange the Bethe-Salpeter equation in ladder approximation for the nucleon is solved. Quark and diquark co…
Baryon Structure in a Covariant Diquark-Quark Model
G. Hellstern, R. Baürle, U. Zückert +2
The baryon structure is investigated in a covariant diquark-quark model. In this approach baryons emerge as relativistic bound states of a constituent quark and a or $1^{+}…
Baryon form factors in a diquark-quark bound state description
G. Hellstern, C. Weiss
Nucleon form factors are calculated in a relativistic diquark--quark picture based on the Nambu--Jona-Lasinio model. The nucleon wave function is obtained in a static approximation…
