Nucleon Form Factors in a Covariant Diquark – Quark Model †
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 confinement is effectively parametrized by choosing appropriately modified propagators. The coupling to external currents is implemented via nontrivial vertex functions for quarks and diquarks to ensure gauge invariance...
متن کاملNucleon Form Factors in the Covariant Diquark–Quark Model
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’s functions. Binding of quarks and diquarks takes place via an exchange interaction and is therefore related to the Pauli principle for three– quark states. Fully Poincaré covariant nucleon amplitudes are calculated fo...

متن کاملK0 form factor and charge radius in a covariant Salpeter model.
The electromagnetic form factor for the K 0 is calculated in a covariant formulation of the Salpeter equation for q ¯ q-bound states, which has been presented recently for the mass spectrum, decay properties and form factors of the light pseudoscalar and vector mesons. The K 0 charge radius dependence on the difference between strange and down constituent quark mass is discussed.
متن کاملForm Factors of 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. This description results as an approximation to the relativistic Faddeev equation for three quarks which yields an effective Bethe-Salpeter equation. Octet and decuplet masses and fully fourdimensional wave functions have been computed for two cases: assuming an esse...
