Determination of proton strange form factors from νpelastic scattering

Abstract

A previous νp elastic scattering experiment at BNL is reanalyzed, taking into account the strange vector and axial-vector form factors of the proton ${\mathit{F}}_1^{\mathit{s}}$, ${\mathit{F}}_2^{\mathit{s}}$, and ${\mathit{G}}_1^{\mathit{s}}$. Values for these form factors are obtained, although with large errors due to correlations between ${\mathit{F}}_1^{\mathit{s}}$ and ${\mathit{F}}_2^2$ and between ${\mathit{G}}_1^{\mathit{s}}$ and the axial vector dipole mass ${\mathit{M}}_{\mathit{A}}$. Future νp elastic scattering experiments could significantly improve the knowledge of these form factors.
