“…This low value of A p 1 (x) at lower and higher values of x be explained on the basis of the sea quarks as in the very low x regime the sea quarks are not highly polarized and at large x there are very few sea quarks and structure is dominated by the valence quarks. For the case of A n 1 (x), the data [62] is negative at low x and becomes positive at large x. In χCQM, the results agree with the data at some values of x and negative values are obtained.…”

“…One should therefore expect the spectrum obtained in the presence of such correlations to be as rich as that allowed by a three-constituent quark model; and this expectation is supported by existing calculations [10,11]. On the other hand, it has been argued that the presence of diquark correlations has a dramatic effect on the contribution from different quark flavours to, inter alia, nucleon elastic electromagnetic form factors [8,12] and parton distribution functions [13]; and, where data exists, the associated predictions are confirmed [14][15][16].…”

In Poincaré-covariant continuum treatments of the three valence-quark bound-state problem, the force behind dynamical chiral symmetry breaking also generates nonpointlike, interacting diquark correlations in the nucleon and its resonances. We detail the impact of these correlations on the electromagnetically-induced nucleon-∆ and nucleon-Roper transitions, providing a flavourseparation of the latter and associated predictions that can be tested at modern facilities.
