Wm. Alberico et al., THE RATIO OF P AND N YIELDS IN NC NU((NU)OVER-BAR) NUCLEUS SCATTERINGAND STRANGE FORM-FACTORS OF THE NUCLEON, Physics letters. Section B, 438(1-2), 1998, pp. 9-13
We calculate the ratio of proton and neutron yields in NC induced nu((
nu)over-bar)-nucleus inelastic scattering at neutrino energies of abou
t 1 GeV. We show that this ratio depends very weakly on the nuclear mo
dels employed and that in nu and (nu)over-bar cases the ratios have di
fferent sensitivity to the axial and vector strange form factors; more
over the ratio of (nu)over-bar-nucleus cross sections turns out to be
rather sensitive to the electric strange form factor. We demonstrate t
hat measurements of these ratios will allow to get information on the
strange form factors of the nucleon in the region Q(2) greater-than-or
-equal-to 0.4 GeV2. (C) 1998 Published by Elsevier Science B.V. All ri
