The ratio of p and n yields in NC v(v̄) nucleus scattering and strange form factors of the nucleon
We calculate the ratio of proton and neutron yields in NC induced v(v̄)-nuc\eus inelastic scattering at neutrino energies of about 1 GeV. We show that this ratio depends very weakly on the nuclear models employed and that in v and v̄ cases the ratios have different sensitivity to the axial and vecto...

| Sumario: | We calculate the ratio of proton and neutron yields in NC induced v(v̄)-nuc\eus inelastic scattering at neutrino energies of about 1 GeV. We show that this ratio depends very weakly on the nuclear models employed and that in v and v̄ cases the ratios have different sensitivity to the axial and vector strange form factors; moreover the ratio of v̄-nucleus cross sections turns out to be rather sensitive to the electric strange form factor. We demonstrate that measurements of these ratios will allow to get information on the strange form factors of the nucleon in the region Q2 ≥ 0.4 GeV2. |
