The cross-section for neutrino-nucleon neutral current (NC) elastic scattering contains the axial vector form factor G_A(Q2) as well as electromagnetic form factors unlike electromagnetic interaction. G_A is proportional to strange part of nucleon spin (Δs) in Q2→0 limit. Measurement of NC elastic cross-section with smaller Q2 enables us to access Δs. Signal of NC elastic scattering is a single proton track. Analysis for the single proton track events using geometrical and dE/dx information of reconstructed track is performed. NC elastic scattering data sample includingνp→νp andνn→νn is obtained. We will report the absolute cross-section as a function of nucleon kinetic energy.
