Description

In this work we present results on the nucleon axial form factor and on correlations between the static electroweak observables by using a scalar spin coupling between quarks fields and nucleon fields in a constituent light front quark model. In the context of the Bakamjian-Thomas (BT) of the quark spin coupling scheme it was shown that the axial coupling constant, the proton magnetic moment and the radius are correlated by model independent relations. We also have studied a comparison between one scale and two scale wave functions, where the introduction of a high momentum scale in the wave function moves the value of square momentum transfer in which the zero of electric form factor is zero improving in such way that the fit of μpGEp/GMp ratio and also preserving static properties of the nucleon obtained in our previous works, where the wave function used was composed by only one scale.
