Query: Strange-quark contribution to the ratio of neutral- to charged-current
  cross sections in neutrino-nucleus scattering   A formalism based on a relativistic plane wave impulse approximation is
developed to investigate the strange-quark content ($g_{A}^{s}$) of the
axial-vector form factor of the nucleon via neutrino-nucleus scattering.
Nuclear structure effects are incorporated via an accurately calibrated
relativistic mean-field model. The ratio of neutral- to charged-current cross
sections is used to examine the sensitivity of this observable to $g_{A}^{s}$.
For values of the incident neutrino energy in the range proposed by the FINeSSE
collaboration and by adopting a value of $g_{A}^{s}=-0.19$, a 30% enhancement
in the ratio is observed relative to the $g_{A}^{s}=0$ result.
