Abstract

For baryons composed by the light quarks (q = u, d) we write spectral integral equation using the notion of two diquarks: (i) axial-vector state,D₁¹, with the spin S_D = 1 and isospin I_D = 1 and (ii) scalar one, D₀⁰, with the spin S_D = 0 and isospin I_D = 0. We present spectral integral equations for the qD₀⁰ and qD₁¹ states taking into account quark-diquark confinement interaction.
