The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; show every role.

A relativistic constituent quark model is used to calculate the semileptonic beta decay of nucleons and hyperons. The parameters of the model, namely, the constituent quark mass and the confinement scale, are fixed by a previous calculation of the magnetic moments of the baryon octet within the same model. We discuss the momentum dependence of the form factors, possible configuration mixing and SU(3) symmetry breaking. We conclude that the relativistic constituent quark model is a good framework to analyze electroweak properties of the baryons.

Comparing with model approaches for the SU(3)-breaking corrections in $f_1(0)$, we note that quark models tend to yield small negative corrections of $-1.3%$ [ref] or $-2.4%$ to $-2.5%$ [ref] for all decay channels, while an analysis based on the $1/N_c$ expansion of QCD [ref] yields positive corrections throughout, ranging from $+2±2%$ for $Λ→p$ to $+7±7%$ for $Ξ→Σ$.

Nevertheless, the contributions of $f_3$, and $g_3$ form factors in Eq. ([ref]) are negligible in comparison with the other form factors since they pick up a factor proportional to the mass of the charged-lepton $m_ℓ$ involved in the transition [ref] .
