We relate ordinary and skewed parton distributions to soft overlap contributions to elastic form factors and large angle Compton scattering, using light-cone wave functions in a Fock state expansion of the nucleon. With a simple ansatz for the wave functions of the three lowest Fock states we achieve a good description of unpolarised and polarised parton distributions at large x, and of the data for the Dirac form factor and for Compton scattering, both of which can be saturated with soft contributions only. Large angle Compton scattering appears as a good case to investigate the relative importance of soft and hard contributions in exclusive processes which are sensitive to the end point regions of the nucleon wave function.

“…This value is compatible with the analysis of the neutrino nucleus total cross section data of refs. [29,30]. On the other hands, these studies, and also other ones done on different target nuclei, show an uncertainty on the axial mass value of 15%.…”

“…It is therefore the aim of this paper to calculate directly the expectation value of the axial vector current (A~(x)) for a self consistent B= 1 solution of the Nambu-Jona-Lasinio model carrying the proton spin and isospin quantum numbers, gA(q 2) is obtained from this by a simple Fourier transformation and can be compared with the experimental data [33][34][35]. At the point q2__0 we can check our result by comparing it with the one extracted from the self consistent ~ field using the PCAC relation [24,[20][21][22].…”

We give a general expression for the expectation value of the axial vector current A~ in a system with baryon number B = 1, which arises as solution of the SU(2)-flayour Nambu-Jona-Lasinio model in the fermion-l-loop approximation. States with good spin and isospin quantum numbers are constructed by using the lowest order cranking approximation. Taking the self consistent solutions for such a system we calculate the axial form factor gA(q 2) and the axial coupling constant gA. The results can be checked by comparing the value of gA with the one obtained from the radial integral or the asymptotic tail of the self consistent pion field by means of the PCAC relation.
